Current advances reveal that high-valence transition metal species critically enhance C–C cleavage during glycerol electro-oxidation, with targeted enrichment of these active sites—via local structure design or in situ reconstruction—proving highly effective. Herein, we engineered a high-entropy FeCrCoNiCu layered hydroxide (HE-LH) catalyst featuring a hybrid quasi-single-crystalline (QSC)/amorphous nanostructure. This design synergistically integrates locally engineered and in situ enriched high-valence active sites for efficient glycerol-to-formate conversion. The high-entropy composition induces a distinctive catalytic ensemble effect, elevating intrinsic GOR activity, while the QSC/amorphous heterostructure maximizes the density of electrochemically (re)active sites. Leveraging this dual optimization, HE-LH achieves an exceptional formate faradaic efficiency of 92.9% and maintains >83% efficiency over five consecutive cycles. This work pioneers a co-design strategy for electrocatalysts by concurrently optimizing active site density and intrinsic activity, establishing high-entropy layered hydroxides as durable platforms for electrochemical biomass upgrading.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 37","pages":" 11491-11499"},"PeriodicalIF":9.2,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100577","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 CH4 selectivity correlates with the Cu (111) facet exposure, which is influenced by the oxidation degree of PANI as well as the size of the deposited Cu. In situ Raman spectroscopy reveals that the sample with an optimal PANI oxidation state (Cu-PANI-48) exhibits the strongest *CO and *COH signals, matching its highest CH4 selectivity.

It operates at high temperatures (3000–6000 K) in non-oxidative environments, achieving superior ethylene yields (50–60%) while eliminating direct greenhouse gas emissions. However, the energy-intensive nature of plasma reactors necessitates evaluating environmental and economic trade-offs. This study evaluates the performances of a modeled plasma naphtha cracking plant across varied operating conditions. When paired with renewable electricity, the emission intensity of produced ethylene decreased to 0.15 kg CO2 eq. per kg C2H4, equivalent to 7.8–11.4% of conventional steam cracking levels. While the levelized cost of ethylene (1.75–2.00 $ per kg C2H4) at an electricity cost of 100 $ per MWhel exceeded the conventional steam cracking by 18–35%, cost parity could be achieved at electricity costs of 40.3–47.9 $ per MWhel under the optimized conditions that also minimized naphtha feedstock requirements. These findings highlight the dual advantages of plasma technology: eliminating direct emissions while enhancing ethylene yield. This research establishes plasma naphtha cracking as a viable decarbonization strategy for ethylene production, underscoring the need for affordable renewable electricity to unlock its full environmental and economic potential.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 37","pages":" 11530-11546"},"PeriodicalIF":9.2,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100581","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}

Femtosecond transient absorption spectroscopy (fs-TAS) provides crucial mechanistic insights via the excited-state behavior, revealing the formation of a catalyst-centered radical anion via substrate-induced electron transfer, and the possible involvement of excited-state intramolecular hydrogen transfer (ESIHT) in governing reactivity. Detailed excited state investigation of the catalyst in the presence of a range of solvents (polar/nonpolar and protic/aprotic) shows, however, that the solvent plays a decisive role in determining the final products arising from the photoinduced transformation. Triplet state sensitization leads to singlet oxygen generation, with the latter reacting with the radical cation generated from the reductive quenching of the photocatalyst, offering precise control over the reaction outcome, enabling selective access to either sulfoxides or sulfones from a diverse array of thioether substrates. The protocol demonstrates broad functional group tolerance and late-stage modulation on drug-like scaffolds, thereby underscoring its synthetic utility. Furthermore, post-functionalization of the resulting sulfoxides allows access to structurally rich frameworks. This study introduces a novel excited-state modulation strategy, expanding the reactivity landscape of organic photocatalysts and providing a foundation for sustainable and switchable transformations in organic synthesis.","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":" 37","pages":" 11500-11509"},"PeriodicalIF":9.2,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100578","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}

Mechanistic investigations combining electron paramagnetic resonance spectroscopy, radical capture experiments and DFT calculations revealed that the spent PM catalysts activate O2 to generate hydroxyl radicals, which promote the oxidative dissolution of the embedded PMs. High-purity Pd and Pt were successfully recovered via a mild lixiviant leaching and N2H4·H2O reduction process, minimizing costs while eliminating the need for harsh acids, toxic cyanides, or volatile organic solvents.

This review summarizes recent advancements in the catalytic reductive conversion of post-consumer PET into fuels, value-added chemicals, and degradable polymers, with a particular focus on heterogeneous catalysis. The catalytic reductive conversion strategies include hydrogenation, hydrogenolysis, hydrodeoxygenation (HDO), and transfer HDO. A variety of products can be obtained depending on the degree of aromatic ring saturation, ester bond hydrogenation, and C–O bond removal. Reaction pathways for achieving target products are outlined. The performance of the catalysts developed is described and compared in each section. In addition, the role of active sites, structure–activity relationships, and reaction mechanisms are comprehensively discussed. Finally, future perspectives are proposed, with specific emphasis on one-pot tandem processes, non-noble metal catalyst design, the production of new chemicals, the impact of additives, elucidation of reaction networks and mechanistic studies.

In this study, environmentally friendly physical and chemical preprocessing strategies for poplar—freeze–thaw and hydrogen peroxide (H2O2) pre-oxidation—were employed to enhance the fractionation performance of an acid/pentanol biphasic system. Freeze–thaw physically disrupted the compact cell wall matrix of poplar, increasing porosity and acid accessibility, resulting in hemicellulose and lignin removal rates increasing from 88.1% and 78.5% (only acid/pentanol pretreatment) to 89.2–89.4% and 85.2–84.8%, respectively. H2O2 pre-oxidation showed superior performance by initiating oxidative cleavage of lignin–carbohydrate linkages (benzyl ether and ester) and depolymerizing native lignin via disruption of β–β and β-5 interunit bonds. These structural modifications reduced lignin condensation, enhanced hydrophilicity, and facilitated subsequent solvent penetration. As a result, hemicellulose removal and delignification reached 92.6% and 90.2%, respectively, while cellulose saccharification efficiency increased to 89.1%. Moreover, the lignin recovered from the organic phase was enriched in phenolic and carboxylic groups, exhibiting enhanced antioxidant capacity. These findings deepened the mechanistic understanding of how oxidative and physical preprocessing facilitated subsequent biomass fractionation and presented a green, modular strategy with strong industrial potential for scalable lignocellulosic biorefinery applications.</div></div>","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":"27 36","pages":"Pages 11075-11092"},"PeriodicalIF":9.2,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057528","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}
