Recent advancements in genetic engineering have produced transgenic trees with reduced lignin content and/or modified lignin structure without compromising growth traits. Here, three engineered poplar varieties are evaluated as feedstocks using a biocompatible one-pot deep eutectic solvent-mediated process that integrates biomass fractionation and enzymatic saccharification within a single reactor, eliminating water washing and reconditioning. All transgenic poplars exhibit higher fermentable sugar yields than wild-type (WT) trees. Notably, QsuB poplar, incorporating 3,4-dihydroxybenzoate in lignin, achieves the highest glucose conversion yield of 91.3% (vs. 73.0% from WT). AT5 and MdCHS3 poplars, incorporating ferulate esters and naringenin, also demonstrate improved glucose yields (86.7 and 84.7%, respectively), confirming reduced biomass recalcitrance. Additionally, residual lignins are valorized via hydrogenolysis into phenolic compounds, with comparable alkylphenol production across all lines. These findings demonstrate that the transgenic poplar lines not only serve as superior feedstocks for sugar conversion but also provide a rich resource for phenolic compound production, enhancing the operational and economic viability of integrated biorefinery processes.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2500891"},"PeriodicalIF":7.5,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The substrate scope included five industrially relevant toluene diisocyanate (TDI)- and methylene diphenyl diisocyanate (MDI)-based carbamates with varied alcohol moieties, representative of intermediates from chemical PU recycling. Notably, TflABH and MthABH are the first urethanases from an esterase superfamily shown to efficiently hydrolyze at least four of the five tested PU-related substrates. Among these, TflABH displayed exceptional thermostability, with a melting temperature (Tm) at least 12 °C higher than those of the other urethanases evaluated. Optimal reaction conditions were established for all three enzymes, revealing pH optima of 7.0 for MthABH, 8.0 for TflABH, and 9.5 for OspAmd, while temperature optima clustered closely around 56-60 °C. Importantly, OspAmd demonstrated greater catalytic efficiency in the hydrolysis of MDA-MeOH, achieving conversions up to 50% after 48 h, approximately threefold higher than benchmark enzymes. These findings highlight the potential of OspAmd, in particular, as a promising biocatalyst for the enzymatic recycling of polyurethanes.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500662"},"PeriodicalIF":7.5,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we demonstrate the fabrication of an electrocatalytic membrane (eCatMem) by laser-induced graphene processing of a gas-separating membrane, enabling CO2 reduction to formate. The membrane exhibits CO2/N2 permselectivity of ~20, ensuring comparable performance when operating with pure CO2 or a 10% CO2/N2 gas mixture. The eCatMem achieves current densities of 10-50 mA/cm2 with a Faradaic efficiency of ~70% for formate production. This is the first of its kind demonstration of integrated membrane electrochemical reactive separation to form a liquid capture media that is also a product. This approach utilizes simple, low-cost materials and processes and offers a scalable way to integrate CO2 capture and utilization.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500474"},"PeriodicalIF":7.5,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144582733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, electron-rich Ru and electron-deficient Ni formed due to the electron migration of Ni→Ru had a synergistic catalytic effect, controlling the precise cleavage of C-N bonds by Ru0 and retaining most of the C-O bonds. The amorphous Al2O3 was sufficiently bound to the substrate to promote rapid hydrogenation. This modification effectively suppressed the intrinsic decarbonylation activity of Ru and improved selectivity for hydrodeoxygenation. Using carbohydrates as substrates, the Ru-Ni bimetallic catalysts preferentially promoted the hydrodeoxygenation pathway, resulting in a significant increase in C3+ monohydric alcohol yields.

However, accessing all the three congeners under a single chemodivergent protocol remains challenging due to the inherent reactivity difference between C=C and C=O bonds. In general, the lower-energy 1,4-addition of a metal hydride preferentially reduces the C=C bond over the C=O bond. Thus, allylic alcohols remain inaccessible with current methodologies. The reactivity of a catalytic reaction can be enhanced under aqueous medium that involves water as a reactant. Additionally, the unique inherent H-bonding network in H2O medium can unlock new reactivity patterns with added sustainability. Herein, we demonstrated a proton-responsive Ir(III) complex catalyzed, base-free, chemodivergent CTH of enones utilizing methyl formate (MF) under aqueous media, enabling precise control over 1,4- vs 1,2- insertion into the Ir-H species. This strategy enabled the selective synthesis of all possible CTH products with high efficiency.

Part of the FexCoy-ZIF (x = 0.05-0.15; y = 0.95-0.85) precursors is directly pyrolyzed to form FexCoy-NPC (NPC-nanoporous carbon), while another part is coated with a silica shell, followed by the pyrolysis of the FexCoy-ZIF@SiO2 intermediates to produce FexCoy-NCF (NCF-nanocarbon framework). To elucidate their chemical, structural, and catalytic properties, the synthesized materials are comprehensively characterized and finally investigate in the base-free oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA). The optimal catalyst (Fe0.15Co0.85-NCF) demonstrates complete conversion of HMF (>99.9%) to FDCA with a pretty high selectivity (82.4%) after 6 h reaction at 80 °C. The correlation of the catalytic features with the efficiency of the catalysts provides insight into the catalytic characteristics responsible for the highest HMF conversion and selectivity to FDCA.

A key breakthrough of this study is the catalytic inefficiency of hierarchically arranged NiZn alloy alone for the SMCC reaction, under visible light illumination. However, upon integrating CdS QDs onto NiZn alloy nanoparticles via nanoscale-interfacial engineering, we observe a remarkable catalytic enhancement. The newly developed NiZn-CdS composite exhibits unprecedented photocatalytic efficiency under visible-light for the SMCC reaction. In contrast, for the AAC reaction, where azides were formed in-situ, the composite demonstrates no catalytic activity under visible light. Interestingly, when CdS QDs are decoupled, the NiZn alloy alone shows outstanding catalytic performance for the regioselective formation of 1,4-disubstituted 1,2,3-triazoles at room-temperature. This represents the first report of a room-temperature, copper-free catalytic system without the use of any noble metal, that outperforms many previously reported copper-free catalysts for AAC, both in terms of activity and selectivity.
