Partial MCR in direct coal liquefaction oil and EmimCl form a DES extractant and can be recycled. The density, viscosity and thermal stability of the extractant were determined experimentally, and the effect of experimental conditions on its separation performance was explored. The structure–activity relationship was explored through visualization of quantum chemistry and molecular dynamics simulation. The in situ DES extraction method and multi-stage flash evaporation combined with the distillation process could effectively remove neutral oil and reduce energy consumption as well as obtain 99.9% MCR product.

Whiteness represents the overall evaluation, which includes greenness (environmental impact) and functional features, represented by redness (analytical efficiency), and blueness (practicality). This work presents the first whiteness assessment model dedicated to chemical synthesis, called “RGBsynt”, inspired by the metrics used in analytics. The assessment may be applied to a set of 2–10 methods, described by parameters such as yield, product purity, E-factor, ChlorTox, time-efficiency and energy demand, which refer to the three primary colours. The model is implemented in an easy-to-use Excel spreadsheet where users input the values of the mentioned parameters, and then data analysis, evaluation and results visualization are carried out fully automatically. The RGBsynt model was employed to compare 17 solution-based procedures for O- and N-alkylation, nucleophilic aromatic substitution, and N-sulfonylation of amines with their corresponding 17 mechanochemical alternatives. The selection of synthesis processes was preceded by a thorough literature review to ensure representative examples and reliable comparison of methods. The evaluation results clearly indicate the superiority of mechanochemistry, both in reducing environmental impact (greenness), and in overall potential (whiteness). The RGBsynt model might be considered as a simple and useful tool for evaluating synthesis methods, allowing comparison of various reactions based on empirical data.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 4","pages":" 1102-1112"},"PeriodicalIF":9.3,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/gc/d4gc05097e?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142993944","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 paper, a synergistic solvent extraction system is described that comprises a liquid ion exchanger (saponified bis(2-ethylhexyl)dithiophosphoric acid) and a lithium-selective ligand (2,9-dibutyl-1,10-phenanthroline) in an aliphatic diluent. The extraction mechanism was investigated and was confirmed to involve the binding of lithium to the selective ligand, while the liquid ion exchanger facilitates the transfer of metal ions from the aqueous to the organic phase. The variables influencing the selectivity for lithium were also determined. The selectivity improved greatly in highly concentrated salt solutions with low concentrations of lithium, rendering the process ideal for the sequestration of lithium from natural brines.

The resulting bio-based polymers exhibited thermal degradation temperatures (Td5%) ranging from 156 °C to 244 °C and glass transition temperatures (Tg) from −8 °C to −36 °C. NMR studies confirmed their polymeric structures and provided insights into the polymers organization, which influenced their properties. These novel polycarbonates were then compared to previously reported polyesters and polyethers derived from similar furan-based α,ω-diene monomers. Additionally, for the first time, co-polymerization studies were conducted on three families of furan-based α,ω-diene monomers—ester, ether, and carbonate—revealing the effect of incorporating different functional groups on the properties of the resulting materials.

The traditional preparation methods of biomass-derived carbon materials, typically in-furnace pyrolysis, involve tedious and energy-consuming processes and require harsh operation conditions. In contrast, laser-induced carbonization is a facile, environmentally friendly and high-efficiency technique that can create an instantaneous thermal shock process for the rapid conversion of biomass into carbon, enabling it to more easily possess unique active sites that play powerful roles in energy storage and conversion applications. Besides, the microstructure and composition of laser-induced biomass-derived carbon materials (LIBCs) can be precisely regulated by adjusting precursor types and laser processing parameters. In this review, the current developments on LIBCs are elaborated. The laser-induced carbonization mechanism is first introduced, and the effects of laser parameters including laser power, scanning speed, laser spot defocus, and atmosphere on the carbonization process are discussed. A special focus is put on the functionalization treatment of LIBCs, including the doping of heteroatoms as well as the incorporation of metals or metal compounds. The applications of LIBCs in the fields of micro-supercapacitors, batteries, electrocatalysis, sensors, and so on are highlighted.

Here, we propose a biomass-based, energy-intensive reduction method to recover Li and Co from spent LIBs. Waste coffee powder was used as a biomass to provide carbon and reducing gas during the reduction process. During selective thermal transformation, the carbon and reducing gas derived from waste coffee powder converted the cathode material of LIBs LiCoO2 into Li2CO3 and Co/CoO, recovering 89.23% of Li and 93.27% of Co. Compared to the conventional carbothermic reduction process, this transformation occurred at a lower temperature (600 °C) due to the synergetic effect of reducing gas and carbon. Moreover, LiCoO2 was regenerated from the recovered Li2CO3 and Co/CoO, demonstrating excellent electrochemical performances in terms of charge–discharge capacity, cyclic performance, rate performance, EIS, and CV curve analysis. An EverBatt-based environmental and economic analysis shows that this reduction method reduces greenhouse gas (GHS) emissions and energy consumption, making it economically viable. Overall, this research offers an eco-friendly and energy-efficient method to recycle spent LIBs using waste biomass.

Among these, acetic anhydride modification is particularly notable, but its low activity necessitates the use of hazardous agents and results in suboptimal mechanical properties after reinforcement. Herein, a solvent-free and recoverable esterification approach was developed to modify pulp fibers with propionic anhydride (PAF). Subsequently, the high-density polyethylene (HDPE) was reinforced at multiple levels through capacity addition, filling, and premixing. The results showed that the optimal mechanical properties and minimum coefficient of thermal expansion (CTE) of HDPE/PAF composites were achieved at a DS value of 0.40. Compared to the unmodified fiber-reinforced composites, propionylation not only improved the discoloration of HDPE/PAF composites but also enhanced its hydrophobicity, as evidenced by an increase in the water contact angle from 89.2° to 103.4°. Moreover, compared to the neat HDPE, the tensile strength and modulus increased by a factor of 2.4 and 3.3, respectively, surpassing the improvements reported for other acid anhydride modifications. These findings indicated that the PAF could be uniformly dispersed in the HDPE matrix through a dual network structure.

Solar-driven interfacial evaporation technology has garnered widespread attention due to its high water evaporation rate and low operational costs. Among numerous interfacial evaporation materials, polyelectrolyte materials (PEMs) exhibit excellent performance in saline water due to the abundant charged structure on their chains, enabling interactions with water and salt ions. This review highlights the unique ionic benefits of PEMs in interfacial evaporation processes. Firstly, the presence of ionic effects allows PEMs to no longer rely solely on capillary action, but instead leverage significant osmotic pressure advantages to enhance water transport. Secondly, in the long-term enhancement of salt tolerance, PEMs do not only depend on structural design but also utilize the Donnan effect, generated by unique ionic interactions, to slow down the crystallization and accumulation of salt ions during ion diffusion and migration. Moreover, due to the anti-polyelectrolyte effect involving salt ions, the ionic chain structure of PEMs generates more intermediate water with low evaporation enthalpy, significantly boosting the evaporation process. This mechanism plays a crucial role in evaporation operations in real water systems. Finally, the tunable ion types in PEMs further broaden their application prospects in interfacial evaporation processes. By adjusting different charged functional groups, PEMs exhibit excellent antibacterial and anti-fouling properties, along with outstanding mechanical performance. Overall, PEMs hold great potential for future applications in water purification via interfacial evaporation.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 4","pages":" 946-958"},"PeriodicalIF":9.3,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142993908","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}

Among various porphyrin derivatives, the tetraphenylporphyrin tetrasulfonic acid (TPPS) additive has the ability to facilitate the formation of a Zn-porphyrin complex to promote uniform Zn2+ deposition, resulting in superior Zn symmetric cells with longer cycling stability over 900 h and smaller overpotential of 35.3 mV. Furthermore, the full cell and pouch-type cell with quinone-fused aza-phenazine (QAP) cathode also exhibit impressive electrochemical performance. Even at different bending angles, the change in specific capacities of pouch-type cells is negligible.
