The solar-driven photocatalytic reduction of CO2 into fuels using a C3N4-based photocatalyst has shown great application potential in addressing challenges related to energy and emission. However, this process suffers from severe charge recombination sluggish H2O oxidation kinetics, resulting low efficiency. In study, 2D/2D S-scheme heterojunction by combining oxygen vacancy-rich BiVO4 nanoflakes with C3N4 nanosheets (denoted as Ov-BVO/CN) was fabricated mitigate the aforementioned issues, where serves water booster center. By leveraging synergistic effects lamellar morphology an charge-transfer pathway, Ov-BVO/CN achieves efficient separation while maintaining maximized redox capabilities. Moreover, theoretical calculations demonstrated that Ov on surface reverses rate-limiting step reducing its barrier, thereby accelerating reaction kinetics. optimized demonstrates remarkably improved evolution rates for CO (13.8 μmol g–1 h–1) CH4 (5.9 h–1), which are approximately 3.8 3.5 times higher than those CN under visible-light irradiation, respectively. This work highlights design fabrication highly heterostructure photocatalysts photoreduction.

Bismuth vanadate (BiVO4), a well-known semiconductor photocatalyst with various advantages, has shown great potential in addressing energy and environmental issues. However, its inherent drawbacks restrict the photocatalytic performance of pure BiVO4. In past few years, many efforts have been devoted to improving catalytic activity BiVO4 revealing degradation mechanism depth. this review, we summarized recent progress on field degradation, including strategies which enhance light absorption ability suppress recombination charge carriers BiVO4, as well related mechanism. Finally, future prospects challenges are summarized, may provide new guidelines for designing more effective BiVO4-based photocatalysts persistent organic pollutants.

Abstract Terminal bifunctional aliphatic compounds are important intermediates for synthesis of drugs, food additives, polymers, while oxidative conversion from diols in mild conditions and the insight mechanism rarely investigated. In this work, Pt‐loaded BiVO 4 (4%Pt/S‐BVO 4%Pt/H‐BVO) is proposed to be utilized oxidation 1,6‐hexanediol (1,6‐HDO). dark conditions, electronic metal‐support interactions between Pt abundant oxygen vacancies (OVs) activated C‐H O 2 , leading primary terminal hydroxyl group 1,6‐HDO. The generated·O − radicals enable further aldehyde carboxyl group. With illumination, photo‐generated holes promoted increased ·O introduced heat originated photothermal effect an additional source supposed boost mass transfer molecules radicals. particular, with more OVs exposed {040} facets, radicals, improved charge separation, 4%Pt/S‐BVO exhibit 90% 1,6‐HDO selectivity 98.6% TBACs 6 h. Those findings highlight great promise catalytic organics transformation by integrating solar energy enhance reaction efficiency.
