Herein, ruthenium/carbon composites are prepared by magnetic induction heating (300 A, 10 s) of RuCl3, RuBr3 or RuI3 loaded on hollow porous carbon cages (HNC). The HNC-RuCl3-300A sample consists of Ru nanoparticles (dia. 1.96 nm) and abundant Cl residues, HNC-RuBr3-300A possesses a larger nanoparticle size (ca. 19.36 nm) and lower content of Br residues, whereas HNC-RuI3-300A, contains only bulk-like Ru agglomerates with a minimal amount of I residues, due to reduced Ru-halide bonding interactions. Among these, HNC-RuCl3-300A exhibits the best HER activity in alkaline media, with a low overpotential of only -26 mV to reach 10 mA cm-2, even outperforming Pt/C, and can be used as the cathode catalyst for anion exchange membrane water electrolyzer (along with commercial RuO2 as the anode catalyst), producing 0.5 A cm-2 at 1.88 V for up to 100 h, a performance markedly better than that with Pt/C. HNC-RuCl3-300A also exhibits the best HOR activity, with a half-wave potential (+18 mV) even lower than that of Pt/C (+35 mV). These activities are ascribed to the combined contributions of small Ru nanoparticles and Ru-to-halide charge transfer that weaken H adsorption.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500802"},"PeriodicalIF":7.5,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148722","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}

This study explored the use of waste fabric as the primary raw material for the development of solar steam generators (SSGs) by harnessing abundant and affordable artificial three-dimensional (3D) structures to deliver an efficient and cost-effective steam-generation solution. The limitations associated with conventional steam-generation methods, such as high costs and the limited availability of suitable materials, were addressed by combining waste fabric with readily available artificial 3D structures. This investigation encompassed the design and fabrication of waste-fabric-based SSGs and evaluated performance, with an emphasis on viability, affordability, and scalability. Cotton fabric heat treated at 400 °C for 1 h exhibited a high light absorbance of 94.7%. In addition, an SSG fabricated using this cotton fabric delivered a high evaporation rate of 2.66 kg/(m2∙h). These findings contribute to the advancement of sustainable and accessible applications in a variety of domains by leveraging the potential of affordable artificial 3D structures for use in SSG applications.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500693"},"PeriodicalIF":7.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148715","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 sacrificial agent-promoted protective strategy that enhances the performance of both the anode and cathode simultaneously. Specifically, the mercapto-containing sacrificial agent adsorbs on the Zn anode, localizing electrons around the thiol group to trigger an in-situ transformation reaction. This reaction forms a modulation layer that optimizes Zn2+ deposition. Concurrently, the agent promotes the formation of a protective MnO2 nanoparticle shell to reduce cathode dissolution. This strategy significantly enhances the cycling stability of both the Zn||Zn and MnO2||Zn cells, achieving 4.5 and 3 times longer performance,respectively,compared to those in ZnSO4 electrolyte.This work presents a simple and efficient dual-function approach that simultaneously stabilizes the Zn anode and suppresses Mn-based cathode dissolution, offering a promising pathway for the practical development of AZIBs.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500680"},"PeriodicalIF":7.5,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148718","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}

Here, we have designed a full storage-release MOST cycle based on the Paternò-Büchi reaction, potentially offering a class of compounds with a significantly higher storage density than NBD-QC. Based on the experimental evidence concerning the viability of their synthesis and photoreactivity, we have repurposed those compounds by computationally elucidating the substitution pattern effects on low-energy isomer's light absorption, followed by high-energy isomer's photoproduction, including singlet and triplet states involved by the Paternò-Büchi type of reactivity.

Despite the great progress achieved in the corresponding photovoltaic devices, the power conversion efficiency (PCE) still lags far behind their theoretical limit. Comparing with the obtained high current density and fill factor, it is of great potential for increasing the open-circuit voltage (Voc) value as the Voc loss of the CsPbX3 perovskite solar cells (PSCs) is still quite significant considering their wide bandgap. The primary mechanisms of Voc loss involve non-radiative recombination driven by bulk defects, interfacial defects and energy level mismatching. To address the above issues, numerous strategies have been investigated including additive engineering, interface modification, charge transport layer replacement, etc. Herein, this review summarizes the most recent work on mitigating Voc loss of CsPbX3 PSCs from three aspects, namely bulk film optimization, interface regulation and transport layer optimization, and gives a brief outlook on how to promote the Voc further. With this, a guideline is provided for researchers engaging in developing CsPbX3 PSCs with high photovoltaic performance.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500428"},"PeriodicalIF":7.5,"publicationDate":"2025-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144141366","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}

This work presents a one-pot two-step linear sequence for the efficient deracemization of β-chlorohydrins by combining a photocatalytic alcohol oxidation with a stereoselective carbonyl bioreduction using alcohol dehydrogenases (ADHs). Despite the thermodynamic challenges of the oxidation step for this family of substrates, three efficient photochemical conditions under white light irradiation were found using catalytic 2,4,6-triphenylpyrylium tetrafluoroborate (TPPT) or 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in this case in stoichiometric or by in situ regeneration of the catalyst. In addition, its sunlight-driven applicability and its implementation in flow chemistry were demonstrated. After testing the scope of these methodologies, 2-chloro-1-arylethanols were found as suitable substrates. For those β-halohydrins oxidized with complete conversion, the deracemization strategy was successfully achieved yielding twelve enantiopure (R)- and (S)-β-halohydrins. Furthermore, 2-chloro-1-phenylethanol enantiomers were subjected to an additional chemical cyclization under basic conditions, providing both (R)- and (S)-styrene oxide in a three-step one-pot process and without loss of the optical activity.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500683"},"PeriodicalIF":7.5,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126388","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 synergistic interplay of electrostatic interactions and controlled molecular entanglement between these macromolecules significantly enhances the stability and ripening resistance of the water-in-oil emulsion. This optimized formulation demonstrates remarkable longevity, maintaining emulsion integrity for over 365 days while exhibiting exceptional salt tolerance and pH stability across various environmental conditions. Additionally, this entangled polysaccharide-based Pickering emulsion demonstrated strong adhesion to leaf surfaces, resisting the effects of strong winds and the water-repellent properties of the lotus leaves. These characteristics associated with microbial compatibility suggest that emulsifiers based on CNCs and CHA provide safer and more sustainable alternatives to conventional surfactants, especially pertinent to the agrochemical sector.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202500723"},"PeriodicalIF":7.5,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126392","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}
