2D/3D BiVO@ZnInS Hierarchical Heterojunction for Enhanced One-Electron Oxygen Reduction Kinetics of HO Artificial Photosynthesis.

Hydrogen peroxide (HO) artificial photosynthesis converts low-density solar energy into storable clean chemical energy, which is an important hot topic in green chemistry. Constructing heterojunctions is an effective tactic to enhance the oxygen reduction kinetics of HO photosynthesis, however, the actual source of activity remains ambiguous. Here, a series of BiVO@ZnInS hierarchical heterojunctions (BZ-, = 0.

Nitrogen vacancy mediated g-CN/BiVO Z-scheme heterostructure nanostructures for exceptional photocatalytic performance.

In this work, a novel V-g-CN/BiVO (V-CN/BVO) Z-scheme heterojunction photocatalyst was formed by introducing nitrogen vacancies (V) and constructing heterojunction, which is able to efficiently degrade the representative contaminant rhodamine B (RhB) upon exposure to visible-light, resulting in an outstanding degradation rate of 98.91% of RhB within 30 min. This photocatalyst exhibits catalytic universality and allows the degradation of methylene blue (MB, 97.
