As the demand for sustainable development and green manufacturing continues to grow in the functional materials sector, the next-generation structural color materials are expected to be prepared with renewable, biocompatible, and biodegradable resources such as lignocellulosic biomass. In this work, we present a fast and low energy-consumption method for converting lignocellulosic biomass to sustainable structural color materials. The lignocellulosic biomass is first treated with an organic–water cosolvent to obtain the extracted solution. Then, the lignin component in the extracted solution, without any purification and fractionation treatment, is assembled into uniform clusters by increasing the water content in the cosolvent to 80 vol%. Finally, the structural color materials are prepared by constructing a periodically ordered array of lignin clusters after centrifugation. The acetone–water cosolvent (6 : 4, v/v) was found to exhibit the best performance for the preparation of structural color materials among 12 different cosolvents, as the extracted lignin in this cosolvent system shows good uniformity and appropriate surface charge. Moreover, the structural color materials obtained from lignocellulosic biomass exhibit tunable colors and good water-responsive properties, and show promising potential as green paints and cosmetics. This strategy greatly simplifies the production process of structural color materials from lignocellulosic biomass, and thus significantly reduces the consumption of energy, time, and solvent compared with the existing methods.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 15","pages":" 3879-3886"},"PeriodicalIF":9.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792992","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}

It is typically synthesized by thermally polymerizing nitrogen–carbon precursors, like melamine or urea, at elevated temperatures (typically ∼550 °C). However, the high energy consumption associated with these methods poses challenges for scalable and sustainable production. Here we develop a functional group engineering to boost the thermal polymerization reaction to produce g-CN at low temperature. When the functional groups phenyl (–Ph), methyl (–CH3), and chlorine (–Cl) substitute the amino (–NH2) group in melamine, the electron density in the triazine ring decreases progressively due to the electron-donating/withdrawing effect. Therefore, the bond energy of –C<img>N– and the stability of the triazine unit would be weakened, consequently boosting the ring-opening reaction. Multiple structural characterization processes confirm that as the withdrawing ability of the functional group increases, the synthesis temperatures of g-CN reduce from about 550 to 300 °C. Our work provides new insights and practical strategies for the sustainable, low-energy synthesis of g-CN, advancing its potential for broader applications.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 15","pages":" 3863-3868"},"PeriodicalIF":9.3,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792990","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}

However, designing high-performance carbonaceous cathodes with accessible active sites and efficient ion transport pathways remains challenging. Herein, we employed a multi-scale assembly strategy to construct lignin-based organic–inorganic supramolecular aggregates (LSA) to prepare nitrogen and oxygen co-doped porous carbon nanosheets (S-NLPC), achieving an exceptionally high specific surface area of 2848.1 m2 g−1, a hierarchical porous structure, and substantial levels of nitrogen and oxygen doping (N: 4.0 at% and O: 8.9 at%). The carbon nanosheets saturated with customized micro–mesopores significantly enhance the kinetics of ion transport and storage, while the nitrogen and oxygen doping improves the accessibility of high-density active sites and introduces additional chemisorption sites. As a result, the ZIHCs utilizing S-NLPC as the cathode demonstrate an enhanced specific capacitance of 433 F g−1 (192.4 mA h g−1), superior energy density of 154.3 W h kg−1 at 80.2 W kg−1, and remarkable cycling stability with a capacity retention of 90.2% after 20 000 cycles at 5 A g−1. Furthermore, ex situ characterization reveals that the superior zinc ion storage performance of S-NLPC is primarily attributed to the reversible chemisorption of oxygen functional groups and the co-adsorption mechanism of Zn2+ and H+. This work presents a novel strategy for constructing lignin-based inorganic–organic aggregates utilizing multi-scale forces, providing new insights into the structural design of carbon-based cathodes for high-performance ZIHCs.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 15","pages":" 3932-3943"},"PeriodicalIF":9.3,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792996","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}

In that frame, terephthalaldehyde (TPA), a non-toxic aromatic dialdehyde, has been selected to replace formaldehyde while resorcinol has been chosen as a replacement of phenol. The syntheses were performed without solvent at temperatures between 150 and 170 °C with a reaction time of around 3 minutes. The resins were synthesized at different TPA-to-resorcinol molar ratios (0.6 and 1.6). This study investigates the mechanism and chemical reactions occurring during the reactive extrusion by characterizing the resin composition through NMR and mass spectrometry (<1500 g mol−1). In addition, differential scanning calorimetry (DSC) analyses were carried out to study the kinetics of the reactions and to estimate the activation energies (32–54 kJ mol−1) through various calculation methods (Flynn–Wall–Ozawa, Friedman, and Vyazovkin methods). It was demonstrated that multiple and consecutive reactions (electrophilic aromatic substitution and condensation) occur during the reactive extrusion process. Additionally, the resins synthesized by reactive extrusion exhibited an exothermic post-reactivity signature in DSC, enabling the estimation of the conversion degrees of 0.63 and 0.59, respectively, for ratios of 0.6 and 1.6. Finally, the resins obtained through reactive extrusion demonstrate great thermal stability even prior to post-heating.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 15","pages":" 3887-3904"},"PeriodicalIF":9.3,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/gc/d4gc05352d?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143792993","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}
