Herein, we design a plasmonic Bi@Vo-Bi2O3 core@shell heterojunction via the hydrothermal method and demonstrate the presence of surface oxygen vacancies identified with electron spin resonance (EPR). Importantly, O2 temperature programmed desorption (O2-TPD) in combination with UV/Vis diffuse reflectance spectra (UV/Vis DRS) revealed the introduction of plasmonic Bi as the core of Bi@Vo-Bi2O3 effectively promotes O2 adsorption by capturing electrons from the defect states and broad the light absorption response range, which synergistically promote catalytic activity on O2 reduction to H2O2 production, pollutant degradation and antibacterial performance in pure water without sacrificial agent. Additionally, the Schottky barrier interface in integrated Bi@Vo-Bi2O3 prevents the excited electrons from recombining with the holes. Furthermore, it was proven that 1O2 played a prominent role in the degradation of Methylene blue, as confirmed by scavenger experiments and detailed experimental characterizations.

Formaldehyde in aqueous solutions can be leached from formaldehyde-containing solid materials (e.g., food, wood, clothes, resins) and absorbed from gaseous formaldehyde by water. Here we developed an enzymatic cleanup technique - the reconstitution of an enzyme cocktail consisting of three coenzyme-free oxidoreductases (i.e., formaldehyde dismutase, methanol oxidase, and formate oxidase) and catalase for the complete oxidation of formaldehyde. This enzyme cocktail catalyzed the reaction of formaldehyde and ambient dioxygen into carbon dioxide (CO2) and water, which was demonstrated by the stable isotope tracer technique. Significant levels of formaldehyde were detected from aqueous solutions leached from the squid, pomfret, fabric, and curtain in the market. When this enzyme cocktail was applied to treat the leachates of contaminated samples above, formaldehyde was eliminated with degradation ratios of up to 100%. This enzymatic cleanup technique, featuring excellent biosafety (for example, degradable catalysts and non-immunogenicity), independence from light, high degradation ratios, and no special equipment required, could be widely used to treat contaminated food, drinking water, and formaldehyde-containing leachate.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402711"},"PeriodicalIF":7.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661715","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, Ni single atoms (NiSAs) and nanoparticles (NiNPs) co-loaded Ti-MOF-derived TiO2 having a flower-like nanosphere microstructure (NiSAs@NPs/TC) was developed for synchronous design of well-defined redox active sites of photocatalytic CO2 reduction and H2O oxidation. It was verified that NiNPs and NiSAs as the active sites of CO2 reduction and H2O oxidation, respectively, synergically accelerated photocatalytic redox reactions and enhanced separation of photo-generated carriers. NiSAs@NPs/TC showed a remarkable photocatalytic CO2-reduction performance (CO and CH4 products: 35.60 and 3.41 μmol g-1 h-1, respectively) in H2O vapour which was at the advanced level in published relevant studies.

Enzyme-photocoupled catalytic systems (EPCS), which mimic natural photosynthesis, utilize solar energy to drive biochemical reactions, providing emergent opportunities to address the limitations of traditional photocatalytic systems. However, the integration and compatibility of photocatalysis and biocatalysis present challenges in designing highly efficient and stable EPCS. Zirconium-based metal-organic frameworks (Zr-MOFs) with outstanding chemical and thermal stability, large surface area, and tunable pore size are ideal candidates for supporting enzymes and enhancing photocatalytic processes. This review aims to integrate Zr-MOFs with EPCS to further promote the development of EPCS. First, an overview of the basic components and design principles of EPCS is provided, highlighting the importance of the unique properties of Zr-MOFs. After that, three different strategies for combining enzymes with Zr-MOFs are summarized and their respective advantages are evaluated. Finally, the development opportunities and some problems to be solved in this field are proposed.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e2402760"},"PeriodicalIF":7.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655832","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 molecular design integrates three phosphonic acid anchoring groups, enabling robust bonding with the substrate to enhance sustainability. Strategically positioned Lewis basic oxygen and sulfur heteroatoms drive synergistic interactions, addressing the limitations of conventional SAMs by optimizing interfacial contact and surface coverage. The face-on orientation of the molecules promotes energy alignment (work function: 5.18 eV) and superior crystallization (grain size: 0.784±0.315 μm).

So far, different experimental procedures (i. e., different solvent, time, etc.) have been used to implement the DPPH methodology without estimating the effect of such modifications on the experimental procedure. To overcome this issue, the impact of the solvent, the time, and the type of substrate on the evaluation of the antioxidant activity (AoA) of lignin via the DPPH assay was investigated in this work. We found that multiple different parameters affect the evaluation of the AoA of lignin: i) the stability of the DPPH radical and the lignin solubility in a given solvent; ii) the importance of reaching steady state (the effect of time); iii) the background noise associated with lignin absorbance at λ=515 nm (used to monitor the DPPH radical scavenging); iv) lignin structure; v) providing a normalized radical scavenging index (nRSI); vi) comparing nRSI vs. inhibition percentage (IP) values. Overall, our investigation allowed us to provide guidelines on how to perform the DPPH assay for a more reliable evaluation of lignin AoA.","PeriodicalId":149,"journal":{"name":"ChemSusChem","volume":" ","pages":"e202402383"},"PeriodicalIF":7.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655757","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 viscoelastic properties of the resulting polymer can be precisely modulated by varying its molecular weight (Mn) and carbonate unit (CU) content, yielding excellent comprehensive performance without the need for additional tackifiers or additives. Notably, PCE9, with a Mn of 90 kg/mol and a CU content of 50 %, exhibited optimal performance, achieving a 180° peel strength of 5.70 N/cm with adhesive failure upon peel-off, and maintaining static shear adhesion for up to 2760 minutes.
