Three boron precursors were introduced into mZVI by ball milling with their physical-chemical properties carefully characterized, and their ability to activate PAA comprehensively evaluated via sulfamethoxazole (SMX) oxidation efficiency. It’s found that BO-ZVI demonstrated the highest capability to activate PAA for SMX degradation, with 2 ∼ 3 times higher than NaBO-ZVI and HBO-ZVI. Specially, B precursors regulate the ability of mZVI to activate PAA via the following two aspects: (1) affecting the formation and content of FeB to accelerate Fe(II) regeneration; (2) increasing the hydrophilicity of the iron particles and the affinity of B-ZVI for binding PAA to different extent. This study highlights the important role of boron precursors in tuning engineered mZVI to initiate Fenton-like process for water purification.","PeriodicalId":516528,"journal":{"name":"Applied Catalysis B: Environment and Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HDU-108 successfully constructed an electron donor-acceptor (D-A) structure using electron-rich thiophene as the electron donor and benzothiadiazole as the acceptor, exhibiting excellent photocatalytic ability due to its structure, which facilitated the spatial separation of charge carriers and reduced charge complexation. This ability was far superior to that of HDU-107. For 10 mg of HDU-108, the efficiency of Cr(VI) reduction in 120 minutes was more than 99.9 %. And the cycle experiments confirmed its good reusability and stability. e played a dominant role in the photoreduction of Cr(VI). Moreover, density-functional theory (DFT) simulations indicated that constructing D-A structures was an effective strategy for modulating photocatalytic activity. The charge separation was triggered by the polarization of the electron-rich BTT nucleus to the local charge density, while the cyanine conjugation provided the active center to concentrate the electronegativity. In conclusion, HDU-108, is expected to be a highly efficient photocatalytic material for environmental remediation.","PeriodicalId":516528,"journal":{"name":"Applied Catalysis B: Environment and Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental results revealed outstanding piezoelectric properties for BiSiO nanosheets with a piezoelectric coefficient of 250 pC/N, outperforming previously reported piezo-photocatalysts. The degradation rate constant of 2,4-DCP on BiSiO nanosheets reached 0.0891 min by piezo-photocatalysis, which is 17 and 1.8 times higher than that by solitary photo- and piezo-catalysis, respectively. Furthermore, DFT calculations for BiSiO explain the crucial role of piezoelectric effects in bending its band structure, regulating photogenerated carrier behaviors, and promoting reactive oxygen species (ROS) generation.

Characterizations and DFT calculations demonstrated that oligomeric MgO species suppress the agglomeration of Pd nanoparticles and strengthen HMF adsorption, consequently promoting total hydrogenation.

The SCOS heterojunction achieved a remarkable yield of 15.90 mmol g h HO production, 3.7 times higher than the base component SCO. The construction of the heterojunction enriched the oxygen vacancies on the catalyst surface, facilitated photogenerated charge separation, and promoted the adsorption of O, reducing the oxygen reduction reaction (ORR) energy barrier. Besides, glycerol served as a unique proton donor, efficiently captured holes to enhance HO production, and generated valuable by-products including glyceric acid and dihydroxyacetone.

Thus-observed anisotropic charge migration of MIL-101(Fe)(112) contribute to 10 times stronger internal electric field (IEF) to accelerate charge separation and migration. Also, we demonstrate the lowest unoccupied crystal orbital (LUCO) of MIL-101(Fe)(112) deepened (up to 3.33 eV vs. NHE) and acquire 3.5 times higher photogenerated holes for robust hole oxidation capacities. As a proof-of-concept, the optimal MIL-101(Fe)(112) can acquire 100 % higher degradation rate and 33 % higher mineralization than MIL-101(Fe)(101).
