Our findings revealed that cellulose and lignin contents tuned the mechanical properties and the wettability of the biocomposites, attributed to their dense intertwined structure and hydrophobicity, respectively. At an optimal composition, namely, C49-K/L40 (49 wt % cellulose at kaolin/lignin = 40 w/w), the composite achieves a compressive strength of 148 MPa and a strain at maximum stress of 37%, exhibiting much higher stress than conventional concrete yet significantly higher strain and, consequently, superior toughness.

Here, a targeted A-site disorder regulation strategy is developed for cobalt-based perovskites by co-introducing Pr, Nd, and Sm into La0.8Sr0.2Co0.7Ni0.3O3–δ to form La0.2Sr0.2Pr0.2Nd0.2Sm0.2Co0.7Ni0.3O3–δ (LSPNSCN).

At 650 °C, LSPNSCN-based R-PCECs deliver a peak power density of 1.58 W cm–2 in fuel cell (FC) mode and an electrolysis current density of –2.32 A cm–2 at 1.3 V in electrolysis cell (EC) mode.

The presence of the carbon substrate effectively inhibits the stacking of MoS2 nanosheets, thereby significantly improving the utilization efficiency of sulfur-vacancy active sites within the structure. In the chemoselective hydrogenation of p-chloronitrobenzene (p-CNB), MoS2@OC achieved 100% conversion with 100% selectivity toward p-chloroaniline (p-CAN) and exhibited excellent stability over five consecutive catalytic cycles. The turnover frequency (TOF) of MoS2@OC for p-CNB hydrogenation reached 15.2 h–1, which is 2.4 times higher than that of MoS2 (6.44 h–1). Hydrogen temperature-programmed reduction (H2-TPR) measurements and density functional theory (DFT) calculations reveal that the interfacial effect at the MoS2@OC interface enhances H2 activation at low temperatures and lowers the hydrogenation energy barrier. In situ Fourier transmission infrared spectroscopy (in situ FTIR) manifests that the adsorption and activation of p-CNB on MoS2@OC are enhanced through interfacial electron regulation. This work provides a promising strategy for the rational design of high-performance MoS2-based catalysts through nanostructure regulation and interfacial engineering.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"168 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209493","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}

Acidic electrolysis avoids this, yet suffers from sluggish oxygen evolution reaction (OER) kinetics, competitive chlorine evolution reaction (CER) from chloride ions, and severe catalyst corrosion. Herein, we construct a Ru/WO3 catalyst with abundant Ru–O–W interfacial bonds for simulated acidic seawater (0.5 M H2SO4 + 0.5 M NaCl). The catalyst requires only 153 mV overpotential to deliver 10 mA cm–2 and operates stably for over 600 h. Notably, excellent performance is also maintained in acidified natural seawater, achieving stable operation at 500 mA cm–2 for 200 h. Remarkably, the introduction of Cl– does not trigger severe chlorine evolution side reactions; instead, it enhances OER selectivity to 93.6% and reduces Ru and W dissolution by approximately 79% and 84%, respectively, relative to the pure acid condition. Mechanistic studies reveal that Cl– preferentially adsorbs on Ru sites to form a Ru–Cl protective layer, blocking OH– attack and high-valent Ru dissolution that occur in the conventional adsorbate evolution mechanism (AEM). Consequently, the active site transfers to adjacent W sites and Ru–O–W bridging oxygen, and the reaction proceeds via the lattice oxygen oxidation mechanism (LOM) to accomplish O–O coupling.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"11 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209537","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}

In this study, iturin A biosynthesis in Bacillus velezensis was enhanced by modifying the genes involved in fatty acid precursors, amino acid precursors, regulators, and transporters, such as accAD, serC, and comA. Additionally, insertion of a terminator–promoter regulatory element into the ituA–ituB intergenic region prevented upstream polar effects and reinitiated downstream transcription, which increased the transcript abundance and stability of the ituB–ituC region to further improve iturin A yield. Optimization of the N-terminal-coding sequence of ituD in the engineered strain ZD-F23 further elevated iturin A yield to 3.85 g/L in shake flasks, representing a 7.95-fold increase over the wild strain ZD122 (0.43 g/L). Finally, iturin A yield was increased to 4.59 g/L in shake flasks by coupling microbial fermentation with Pickering emulsion techniques in an optimized oil-in-water system. This value represented the highest iturin A titer among previous B. velezensis strains. In summary, this study establishes a multilevel engineering strategy integrating transcriptional reprogramming with emulsion-based fermentation, demonstrating the potential for scalable biomanufacturing of iturin A.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"11 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209546","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}

Precursor chemistry plays a critical yet underexplored role in regulating the spatial distribution and catalytic accessibility of iron in carbon-based photo-Fenton catalysts. Manipulation of Fe sites distribution to tune catalytic accessibility of Fe on carbon dots (CDs) constitutes a topic of vast interest and a challenging pursuit. Here, we report a precursor-directed strategy to develop Fe atomically surface-accessible CDs (Fe-SACDs), with excellent response to simulated solar light, using shrimp-extracted chitin as a precursor. A controlled spatial distribution of atomically dispersed Fe centers was enabled by the abundant nitrogen- and oxygen-containing functional groups in the chitin precursor. The surface-accessible Fe species enabled robust Fe(II)/Fe(III) cycling, which enhances the generation of reactive species for catalysis of organics in water. These advantages afforded highly efficient degradation of methylene blue (∼100% removal) with improved structural stability (more than 5 cycles) and broader pH adaptability (3–12) compared to nonsurface-accessible controls where Fe is absent (CDs) or not atomically dispersed (Fe-CDs). This study reveals how a precursor-directed control of Fe spatial distribution governs the performance of photo-Fenton catalysis, inspiring a new strategy for designing efficient biomass-derived carbon catalysts for advanced water decontamination.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"34 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209548","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}

Integrated CO2 capture and utilization (ICCU) has been proposed to eliminate the desorption and compression steps; however, the complexity of ICCU potentially shifts energy demands elsewhere, impacting the overall economics. This work evaluates whether ICCU offers economic and environmental advantages over a conventional CCU process (CCU-MEA case). Experimental methanol activities for two ICCU solvent systems of hexanol–triethylamine (ICCU-NEt3 case) and ethylene glycol–tetramethyl-1,6-hexanediamine (ICCU-TMHDA case) were collected for process simulations. ICCU cases reduced energy requirements in CO2 capture while increasing energy use in purification steps due to higher distillation loads, revealing a trade-off between capture savings and separation costs. CO2 capture capacity strongly influenced the minimum methanol selling prices as ICCU-TMHDA and CCU-MEA cases achieved 1997 and 1959 USD/t, respectively, while the ICCU-NEt3 case reached 5687 USD/t due to limited capture performance. Increasing the solvent flowrate in the ICCU-NEt3 process reduced the minimum selling price to 1735 USD/t. The presented results emphasize that high CO2 capture capacity and methanol activity are decisive for making ICCU both economically and environmentally viable, providing guidance for designing industrial ICCU systems for methanol synthesis.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"45 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149209539","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}
