Enzymatic hydrolysis using the selective lipase from Pseudomonas cepacia, initially performed in aqueous buffer systems and subsequently in the presence of organic cosolvents, showed limited efficiency, likely due to limited enzymatic accessibility within the complex multiblock architecture. In contrast, homogeneous organocatalytic approaches showed higher degradation efficiency and selectivity. Base-catalyzed transesterification using 4-dimethylaminopyridine (DMAP) and imidazole enabled 100% selective chain scission toward lactyl units. Brønsted acid catalysis with p-toluenesulfonic acid (pTSA) and diphenyl phosphate (DPP) exhibited complementary transesterification selectivity, favoring degradation of caprolactoyl units and thus targeting the soft segments. The latter selectivity is particularly interesting, as it provides structural information about the chain-shuttled copolymers and allows to envision recycling of the PLA part. It is corroborated by DFT studies.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 21","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cssc.71174","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149293512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we demonstrate that lattice sulfur in transition-metal sulfides can serve as a reactive sulfur source for heteroatom-exchange sulfurization, enabling the conversion of biomass-derived furans into thiophene derivatives. A series of Fe(1−x)NixS2 bimetallic sulfides were synthesized via a one-step hydrothermal method and evaluated as stoichiometric sulfurization reagents for converting 5-hydroxymethylfurfural (HMF) and cellulose to methyl 5-(methoxymethyl)thiophene-2-carboxylate (MMTC). Fe0.5Ni0.5S2 exhibited the highest sulfurization performance, affording an MMTC yield of 10.8 wt% from HMF and outperforming all other compositions. Raw cellulose was also converted to MMTC with a yield of 3.9 wt% through direct heteroatom-exchange sulfurization. Characterization results suggest that the enhanced sulfurization performance of Fe0.5Ni0.5S2 correlates with balanced surface acidity and an increased proportion of lattice-derived S22− species, which participate in sulfur transfer during heteroatom exchange. A plausible reaction pathway is proposed to rationalize MMTC formation. This work establishes a proof-of-concept strategy that lattice sulfur in transition-metal sulfides can directly participate in biomass-derived heteroatom-exchange sulfurization, providing a conceptual foundation for sulfur-mediated biomass valorization.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 21","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149293513","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}

Biophotoelectrochemical (BPEC) systems are promising platforms that couple the light-harvesting capability of semiconductor photocatalysts with the catalytic precision of biocatalysts using an electrically addressable electrode. BPEC systems provide tunable reaction pathways, improved scalability, easier product handling, and flexibility in coupling various reactions by modifying the electrode architecture. This review presents a comprehensive discussion of these architectures in BPEC systems, beginning with the fundamental principles of how photoelectrodes and bioelectrodes work. This review then provides a systematic examination of two different electrode architectures: separated electrodes (photoelectrode | bioelectrode) and biohybrid photoelectrodes (biophotoelectrodes). The discussion covers their configurations, working principles, and representative applications such as H2 evolution, CO2 reduction, N2 fixation, pollutant removal, and energy recovery. The review also summarizes key performance metrics and current research trends. By integrating the complementary strengths of photoelectrodes and bioelectrodes, BPEC systems can overcome individual technological limitations and support sustainable energy and environmental applications through self-biased operation and enhanced product selectivity. Finally, the review discusses the challenges and future directions of advancing BPEC systems into scalable, multifunctional platforms for next-generation sustainable technologies.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 21","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13717573/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149293472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, through a facile Fe3+ impregnation of a pristine Fe–N–C support followed by thermal activation, we achieved a hundred-gram-scale synthesis of a high-quality Fe–N–C synergistic catalyst comprising Fe–N4 and Fe ACs/NPs. By comprehensive structural characterizations and theoretical calculations, we demonstrate that the enhanced apparent ORR activity originates from the electronic modulation of Fe–N4 sites by their adjacent acid-resistant Fe ACs. The optimized catalyst achieves a record-high half-wave potential of 0.950 V and a kinetic mass-specific activity of 69.8 A g−1 at 0.90 V in alkaline medium among the reported Fe–N–C catalysts. This catalyst as ZAB cathode delivers an outstanding peak power density of 201 mW cm−2 with superior long-term stability, far surpassing the benchmark Pt/C.

Compared to the conventional adsorbate evolution mechanism (AEM), more resonant vibrational responses in the lattice oxygen mechanism (LOM) promote the bond formation and facilitate catalytic efficiency. Here, we reveal the intrinsic mechanism of the AEM–LOM transition from a vibrational perspective induced by localized lattice softening. Using spinel Co3O4 as a model system, theoretical calculations show that Yb introduction lowers the energy barrier of the potential-determining step from 1.794 to 1.048 eV and enables direct lattice oxygen involvement. Phonon density of states (DOS) analysis further reveals that Yb introduction softens the local Co-O framework and modifies the lattice response to oxygen-vacancy (VO) formation. The redistribution of phonon modes and weakened Co–O vibrational coupling induced by the local octahedral distortion lead to lattice softening. Factor group analysis and irreducible representation decomposition further support that the lattice symmetry breaking in Yb-doped Co3O4 is the structural origin of the lattice softening. This work provides a vibrational interpretation of OER mechanism switching in spinel Co3O4, offering theoretical insights for the development of more efficient OER electrocatalysts.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 21","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149293545","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}

Platinum (Pt) remains irreplaceable for commercial PEMFCs. Although there have been many efforts to improve performance of Pt through alloying, insufficient stability remains a major challenge. Herein, we report a sub-3-nm ordered phase Pt2MnZn intermetallic compound (IMC) on carbon black (O-Pt2MnZn) that achieves superior activity and durability for ORR. The electronegativity differences among Pt, Mn, and Zn endow the alloy with intrinsic thermodynamic stability, while the ordered structure provides beneficial strain and coordination effects. O-Pt2MnZn exhibited a high mass activity of 1.15 A mgPt−1 and 88.7% retention after 10,000 accelerated stress test (AST) cycles in rotating disk electrode. In practical fuel cells with an ultralow cathode Pt loading of 0.05 mgPt cm−2, O-Pt2MnZn delivered a peak power density of 0.85 W cm−2 and 95.3% retention after 10,000 AST cycles, far exceeding commercial Pt/C (0.75 W cm−2, 69.3% retention).

Therefore, developing acidic OER catalysts that simultaneously exhibit high intrinsic activity with long-term stability remains a core scientific and engineering challenge for the practical deployment of PEMWE. This review first outlines the fundamental mechanisms of acidic OER, including the adsorbate evolution mechanism (AEM), the lattice oxygen mechanism (LOM), and the oxide path mechanism (OPM). It then summarizes recent advances in catalyst design and structure–property relationships, with emphasis on strategies for stabilizing Ru-based catalysts, reducing Ir loading while enhancing site efficiency in Ir-based systems, and developing platinum group metals (PGM)-free catalysts featuring acid-stable frameworks, corrosion-resistant architectures, and improved electronic conductivity.
