Lignin in lignocellulose is generally removed by alkaline pretreatment (e.g., NH4OH, ethanediamine), while the severe environment causes equipment corrosion and forms toxic inhibitors. Using ─NH2/NH4+-derived acidic compounds (ADACs) might achieve ideal lignin removal efficiency and fermentability. Herein, five ADACs including ammonium chloride (AC), ammonium sulfate (AS), ammonium acetate (AA), butanamide (BuA), and sulfamic acid (SuA) were used for corn stover (CS) pretreatment. The xylan removals were 16.69%–39.49% when pretreating CS by ADAC at 150 °C, which resulted in lower glucose yields of <65%. Elevating the temperature to 180 °C improved lignin and xylan removals to 64.93% and 92.57% under SuA pretreatment. In this case, glucose yield reached 88%, which was 4.27-fold to that of untreated CS. The fermentability of ADAC-pretreated CS hydrolysates was then used for bioethanol production. The obtained ethanol yields reached 88.03% (AC), 72.52% (AS), and 83.35% (SuA). Meanwhile, approximately 25 g/L ethanol was produced by Saccharomyces cerevisiae from SuA-pretreated hydrolysates containing ~60 g/L glucose. Overall, it is the first report to evaluate the typical ADACs for lignocellulose fractionation, which exhibits considerable potential for bioethanol production.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 19","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068923","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}

Although III–V semiconductors exhibit exceptional optoelectronic properties, their reliance on platinum group cocatalysts limits scalability. Here, we report a platinum group metal-free (PGM-free) hybrid photocathode integrating an epitaxially grown GaAs/Si:p junction with mixed-phase MoS2 nanostructures for efficient hydrogen evolution in acidic media. Through systematic control of morphology, crystallinity, and phase composition, we demonstrate that 1T′-rich MoS2 nanoflowers outperform exfoliated nanosheets, bulk 2H-MoS2, and amorphous powder MoSx. The nanoflower architecture delivers higher saturation photocurrent densities and a positive shift in onset potential, attributed to enhanced charge transport, catalytic kinetics, and light penetration, while simultaneously improving stability. Notably, the hierarchical nanoflower morphology and 1T′ phase synergistically enhance photocurrent performance. The optimized GaAs/Si:p photocathodes modified with MoS2 nanoflowers exhibit stable operation with a Faradaic efficiency of ~97% for hydrogen evolution. These findings establish morphology-phase synergy as a critical design principle for developing PGM-free PEC systems, paving the way for cost-effective solar fuel production.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 19","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cssc.71110","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048573","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, a potassium phosphotungstate/carbon nitride nanosheet (KPW/CNS) heterojunction was constructed through a facile electrostatic assembly strategy for photocatalytic CO2 reduction. The optimized photocatalyst (5KPW/CNS) exhibited CH4 and CO evolution rates of 6.3 and 9.3 μmol g−1 h−1, respectively, corresponding to a CH4 selectivity of 40% and excellent photostability. In comparison, pristine CNS produced only 0.4 μmol g−1 h−1 of CH4, and showed a much lower CH4 selectivity of 7.0%. Combined X-ray photoelectron spectroscopy, Kelvin probe force microscopy and density functional theory calculations revealed the formation of built-in electric field at the KPW/CNS interface, which drives an S-scheme charge–transfer pathway and promotes efficient spatial separation of photogenerated charge carriers. More importantly, mechanistic investigations demonstrated a cooperative catalytic pathway involving both components of the heterojunction. CNS primarily acts as the electron-enriched site for CO2 adsorption and activation to form *CO intermediates, whereas KPW facilitates the subsequent hydrogenation of *CO toward *CHO, *CH2O, and ultimately CH4. This synergistic interaction promotes the CO2-to-CH4 conversion pathway and accounts for the enhanced CH4 selectivity of the KPW/CNS heterojunction.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 19","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048574","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}

Lignocellulosic biomass (LCB) represents the largest natural carbon resource on the planet and is made up of cellulose, hemicellulose, and lignin, yet it is still primarily used for low-value products. To advance the field, the capability of biomass as a feedstock for advanced materials necessitates viewing deconstruction and reconstruction not as distinct processes but as a unified, codesigned route. This review enhances that viewpoint by employing the “deconstruction–reconstruction” framework to link biomass fractionation with the potential products generated from it. We critically assess mild activation, component fractionation, and partial degradation through their ability to preserve the functional groups and structural motifs that govern downstream performance. Building on this, we map reconstruction pathways from biomass-derived macromonomers into thermoplastics, thermosets, gel systems, vitrimeric elastomers, coatings, and adhesives. By linking these relationships back to deconstruction chemistry, the review identifies feedstock–process–property combinations that enable high-value circular materials. Finally, we identify the barriers that still limit scale-up, namely feedstock variability, lignin heterogeneity, and solvent recovery, and outline data-driven and green-chemistry strategies for the rational design of circular lignocellulose-based materials.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":"19 19","pages":""},"PeriodicalIF":5.9,"publicationDate":"2026-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048595","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}

Herein, we propose a facile, one-step liquid-phase mediated method to directly repair S-LFP. By constructing a liquid-phase-mediated system comprising Fe/Li-based salts and sucrose, this method kinetically accelerates ionic diffusion and ensures homogeneous elemental distribution at a low temperature (300 °C). Concurrently, the synergistic effect of the liquid-phase-mediated state and a reducing atmosphere facilitates the complete structural restoration from Fe3+ to electrochemically active Fe2+. Consequently, the regenerated LFP (R-LFP) demonstrates exceptional electrochemical reversibility, delivering a superior initial capacity of 158.5 mAhg−1 at 0.1 C. Notably, practical full-cell evaluations exhibit robust long-term cycling stability, retaining 80.0% capacity over 1500 cycles at a high rate of 2 C.

To simultaneously stabilize the Zn anode and the NaV3O8 (NVO) cathode, we propose a synergistic strategy based on mixed organic phosphate additives, which integrates triethyl phosphate (TEP) for bulk modulation and tris(2,2,2-trifluoroethyl) phosphate (TFEP) for interfacial regulation. Experimental and computational investigations reveal that the TEP molecules actively participate in the Zn2+ solvation sheath and disrupt the hydrogen-bonding network of water. Meanwhile, the TFEP molecules preferentially adsorb onto the electrode surface and undergo reductive decomposition to construct a robust composite solid electrolyte interphase (SEI). The SEI, consisting of an inorganic-rich inner layer and an organic-rich outer layer, physically isolates the anode from active water and suppresses dendrite growth. Furthermore, the adsorbed TFEP contributes to the formation of a cathode electrolyte interphase (CEI) at the NVO cathode. Consequently, Zn||Zn symmetric cells achieve an extended cycling lifespan over 550 h at 10 mA cm−2 and 10 mAh cm−2, and Zn||NVO full cells exhibit excellent cycling stability with 92.6 % capacity retention after 500 cycles at 1 A g−1.

Herein, zinc pentafluorophenyl porphyrin (ZnPF) derivatives are developed as supramolecular passivators through p-selective nucleophilic aromatic substitution and incorporated into perovskite films via a green anisole-based antisolvent strategy. Systematic variation of the aromatic substituents provided insight into the relationship between molecular structure, supramolecular packing, and defect passivation. In particular, the p-phenoxy substituent in ZnPF-2 balanced steric effects and promoted ordered molecular packing, leading to more effective interfacial passivation. This multifunctional passivation improved perovskite crystallinity and charge-carrier transport while suppressing non-radiative recombination and interfacial leakage currents. Consequently, ZnPF-2-modified devices achieved a remarkable power conversion efficiency (PCE) of 34.29% under 1000 lx illumination, while also showing consistent gains under AM 1.5G conditions and in a compositionally distinct perovskite system, supporting the transferability of the strategy. Moreover, the hydrophobic ZnPF modification improved long-term durability, with devices preserving over 90% of their initial efficiency after 1600 h under ambient storage.
