Опубликована: Апрель 19, 2024

A lack of eco-friendly, highly active photocatalyst for peroxymonosulfate (PMS) activation and unclear environmental risks are significant challenges. Herein, we developed a double S-scheme Fe2O3/BiVO4(110)/BiVO4(010)/Fe2O3 to activate PMS investigated its impact on wheat seed germination. We observed an improvement in charge separation by depositing Fe2O3 the (010) (110) surfaces BiVO4. This enhancement is attributed formation dual transfer mechanism at interfaces Fe2O3/BiVO4(110) BiVO4(010)/Fe2O3. By introducing into system, photogenerated electrons effectively PMS, generating reactive oxygen species (ROS) such as hydroxyl radicals (·OH) sulfate (SO4·–). Among tested systems, 20% Fe2O3/BiVO4/Vis/PMS system exhibits highest catalytic efficiency norfloxacin (NOR) removal, reaching 95% 40 min. twice Fe2O3/BiVO4/PMS 1.8 times that Fe2O3/BiVO4 5 BiVO4 system. Seed germination experiments revealed heterojunction was beneficial germination, while had negative effect. study provides valuable insights development efficient sustainable photocatalytic systems removal organic pollutants from wastewater.

Abstract Acetaldehyde (CH 3 CHO) is of great industrial importance and serves as a key intermediate in various organic transformations. Photocatalytic production acetaldehyde from CO 2 represents sustainable route compared to conventional oxidation processes. However, current photocatalytic systems often face challenges, including limited product selectivity dependence on sacrificial reagents. Here, we present Cd 0.6 Zn 0.4 S (CZS) photocatalyst co‐modified with sulfur vacancies atomically dispersed Cu (Cu/CZS−Vs) for the efficient conversion acetaldehyde. Charge density analysis reveals that induce charge accumulation around adjacent metal atoms, creating active sites strongly anchor H + , thereby promoting while suppressing competing hydrogen evolution reaction.

Optimization of Adsorption Sites for Selective Hydrobenzoin and Syngas Production in a Single Photoredox Cycle

Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Май 2, 2025

Abstract Integrating benzyl alcohol oxidation with carbon dioxide (CO 2 ) reduction in a single photoredox catalysis is of high economic and practical interest. However, it remains challenging to controllably regulate the selectivity specific C─C coupling chemicals (oxidation products) ratio monoxide hydrogen (CO/H for syngas (reduction products). Herein, an efficient photocatalyst consisting CdS nanorods decorated by Ni P (NP/CdS) developed, which achieves remarkable performance, producing hydrobenzoin (HB) excellent yield ≈315.4 µmol g −1 h ≈90%. This performance originates from optimized adsorption benzaldehydes protons, promoting generation critical radical intermediates (•CH(OH)Ph). Meanwhile, favorable desorption •CH(OH)Ph HB binding sites attained. On other hand, increasing content NP/CdS, CO/H can be adjusted across wide range (from ≈15:1 ≈2.6:1), enabling compositions suitable industrial feedstock applications. tunability attributed lower CO affinity phase compared while demonstrating higher activity H evolution. work presents novel approach selectively efficiently tunable simultaneously.
