Multi-channel charge transfer of double Z-scheme LaVO4/WO3@HxV2O5 heterojunction for efficient visible-light photo-thermo synergy oxidation of cyclohexane
The photo-thermo synergy catalytic cyclohexane oxidation has been identified as an efficient and environmentally friendly approach for the preparation of cyclohexanone and cyclohexanol (KA oil). However, this strategy encountered several challenges that impeded its implementation for the one-step production of adipic acid (AA), highlighting the need for further advancements. Herein, a robust strategy for tailoring multi-channel charge transfer pathways in LaVO4/WO3@HxV2O5 nanospherical composites was developed by constructing double Z-scheme heterojunctions. The LaVO4/WO3@HxV2O5 exhibited exceptional photothermal catalytic performance for the cyclohexane oxidation, achieving the cyclohexane conversion of 11.01 % with the total selectivity of 96.38 % (solid product AA of 58.51 % and liquid product KA oil of 37.87 %). The exceptional performance of LaVO4/WO3@HxV2O5 can be ascribed to the double Z-scheme heterojunctions with multi-channel charge transfer and high redox potentials, which facilitates the efficient separation and transfer of photo-generated electron-hole pairs. This deliberate design of double Z-scheme heterojunctions provides valuable insights into the meticulous construction of efficient pathways with multi-channel charge transfer for the field of photothermal catalysis applications.
