Herein, we report a novel 1D carbon nanotube-modified 3D hollow carbon sphere with a hierarchical structure and strong interfacial interactions. Good surface dispersion of the bimetal seeds on the carbon sphere can achieve uniform growth of curly CNT arrays. The porous 3D carbon skeleton can provide support structures to stabilize NiFe seeds for uniform growth of the CNTs and the carbon layer; thus abundant FeNi3/(NiFe)9S8 heterostructures encapsulated inside the 1D/3D skeleton can act as spatially dispersed active sites to accelerate reaction kinetics. Moreover, the multilevel 1D/3D structure with high porosity and hydrophilicity can promote the infiltration of electrolyte into the internal structure, thus constructing an optimal gas–solid–liquid interface to enhance the electrocatalytic process. Therefore, N–HCS@NiFe can achieve an overpotential and potential of 228 mV and 1.348 V vs. RHE at 10 mA cm−2 for the oxygen evolution reaction (OER) and the urea oxidation reaction (UOR), respectively, while the half wave potential and average electron transfer number of N–HCS@NiFe for the oxygen reduction reaction (ORR) are 0.80 V vs. RHE and 4.0, as well as excellent long-term stability at high current density for various reactions. This work provides a new strategy for the rational 1D/3D structural design and active metal spatial dispersion of multifunctional electrocatalysts for green and sustainable energy conversion applications.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 12043-12052"},"PeriodicalIF":9.3,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The merits of this approach include the use of air as the oxidant and abundant metal recyclable catalyst, free of additives, high step and atom economy, and broad substrate scope, showing great potential for application in drug synthesis. The mechanistic insights are also gained: (1) ethanol dehydrogenation is the rate-determining step of this reaction, which is mainly implemented by ˙O2−; (2) the CoN4 site exhibits a strong ability for adsorption of O2 and ethanol, and it has the lowest ethanol dehydrogenation energy barrier than CuN4 and FeN4.

Anaerobic digestion for producing methane is the most effective method for utilizing food waste resources. However, the by-product, food waste digestate (FWD), is rich in C/N/P. Direct discharge of FWD may cause significant environmental burdens and lead to the loss of valuable resources. In this study, we established a system to convert FWD into the high-value agricultural antibiotic streptothricin F through biological fermentation by Streptomyces lavendulae and simulated moving bed (SMB) separation for energy and resource recovery. After biological fermentation, the concentration of streptothricin F in the co-fermentation of FWD and soluble starch by Streptomyces lavendulae reached 0.5144 g L−1, and its concentration was 60.51 times higher than in the control. The COD conversion rate reached 82.50% after biological fermentation, achieving high-value utilization and harmless treatment of FWD. Streptothricin F was effectively separated using SMB technology, achieving a high purity of 97.47% and a recovery rate of 91.16%. Additionally, streptothricin F showed inhibitory effects against Alternaria, Fusarium oxysporum, and Colletotrichum, indicating its broad-spectrum antifungal properties. The pure streptothricin F obtained through SMB separation against Alternaria had an EC50 value of 0.66 μg mL−1, representing an 81.24 times improvement in antifungal activity compared to the unpurified fermentation broth (53.62 μg mL−1). Life Cycle Assessment (LCA) results indicated that the system had a relatively low environmental impact. This research presents a novel strategy for the high-value utilization of food waste digestate, advancing the technological level of biomass utilization.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 11963-11975"},"PeriodicalIF":9.3,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The construction of high-efficiency batteries remains a significant obstacle to the further advancement of novel battery types and enhanced electrochemical performance. Nowadays, cellulose, an abundantly available biopolymer, is garnering attention as a promising green material for energy storage devices, particularly zinc ion-based energy storage devices. Its unique characteristics such as renewability, biodegradability, and excellent chemical stability make it a versatile candidate for various components of zinc-ion energy storage systems. By strategically modulating the properties of cellulose, advanced materials can be developed to enhance the capabilities of zinc-ion storage devices. This review summarizes the structures and characteristics of cellulose before delving into the recent progress achieved in research on zinc-ion energy storage systems using cellulose-based materials. These advancements include cellulose-derived carbon materials for zinc-ion capacitors, flexible zinc-ion capacitors based on cellulose-derived substances, cathodes incorporating cellulose-based hybrids and binders, anodes with cellulose host architectures, surface-modified, self-supporting cellulose separators, cellulose modification of separators, cellulose gel electrolytes and electrolyte additives, and there are prospects for future applications of cellulosic materials in zinc-ion energy storage systems. Through strategic modulation of their properties, the adaptability and efficiency of cellulosic materials in various components of zinc-ion energy storages can be significantly enhanced. Further studies focusing on innovative approaches for modifying, optimizing, and designing cellulosic materials are expected to unlock new avenues for sustainable high-performance energy storage applications.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 2","pages":" 325-351"},"PeriodicalIF":9.3,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142870229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Common raw materials are non-renewable and oil-derived while requiring large amounts of (toxic) chemicals and energy for their processing into final products. In addition, synthetic textiles are usually non-biodegradable polymers; therefore, sustainable approaches for their depolymerisation into reusable monomers have not been implemented yet. As a result, most post-consumer synthetic textile waste ends up being landfilled, dispersed in the environment or incinerated, thus contributing significantly to global pollution. A possible solution to this issue is the design and use of advanced catalysts for their chemical recycling. This manuscript reviews the most significant approaches that appeared in the literature in the time span of 2015–2024, covering the selective depolymerisation process of synthetic waste textile to added-value reusable monomers using chemical catalysts. Unselective processes, for example, to produce fuel mixtures, biocatalytic methods and depolymerisation of polyolefins are not covered. The general aspects of the catalytic depolymerisation of synthetic polymers are briefly discussed, and the catalytic chemical recycling of synthetic textiles is detailed by the polymer type. While contributing to the overall achievement of the sustainable development goals, chemical recycling of synthetic textile waste may represent a useful strategy toward the circularity of the textile sector, which is almost unexplored.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 11832-11859"},"PeriodicalIF":9.3,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/gc/d4gc04768k?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chlorine group in CMF introduces fundamental differences and creates new potential compared to the HMF molecule. This group leads to higher hydrophobicity properties and facilitates extraction from the reaction medium, and also improves the stability and reactivity of CMF, which makes this platform a milestone in the synthesis of value-added chemicals from biomass. CMF, as a fascinating platform, can be obtained from a range of biomass feedstocks, while HMF is only practically prepared at scale from fructose.

This study demonstrates the efficacy of CO2 as a metal-free catalyst for the chemical recycling of common waste polyester and polycarbonate plastics via alcoholysis to yield valuable organic chemicals. CO2 was proposed to act as a Lewis acid–base pair, activating both alcohol and ester (carbonate) functional groups during the catalytic process. The depolymerization mechanism was thoroughly investigated by monitoring conversion rates and changes in Mn values. Pre-treatment of the polymer materials in THF was found to accelerate the depolymerization rate. End-of-life waste materials were completely degraded into valuable organic molecules, irrespective of their physical and chemical properties. Unlike conventional solid and liquid catalysts, CO2 leaves no residue in the final products. Moreover, this work unveils the catalytic role for CO2, expanding its traditional function as a C1 building block in synthetic chemistry.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 24","pages":" 11976-11983"},"PeriodicalIF":9.3,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/gc/d4gc04782f?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we introduce an innovative approach to PN synthesis, utilizing 4-chlorophthalonitrile as the starting material. This “utilize rather than create” strategy employs the reaction product (RPH) as the precursor and the by-product (KCl) as the template for the synthesis of porous carbon (RKC). The formation mechanism of RKC is elucidated through TGA/FTIR and TGA/MS analysis. The resultant RKCs exhibit exceptional characteristics suitable for supercapacitor applications, including hierarchical micro-/meso-/macropores, an extensive specific surface area, a high N-doping level, and diverse N species (N-6, N-5, N-Q). RKC@600 achieves a remarkable specific capacitance of 300 F g−1 at 1 A g−1 and demonstrates impressive cycling stability with a retention of 96.1% capacitance after 10 000 cycles at 10 A g−1.
