EPR Investigation on Electron Transfer of 2D/3D g‐C₃N₄/ZnO S‐Scheme Heterojunction for Enhanced CO₂ Photoreduction

Photocatalytic conversion of CO 2 into useful products is a promising technology from environmental and economic viewpoints. However, the efficiency of current photocatalytic materials is still unsatisfactory. In this work, a robust S‐scheme heterojunction composed of 3D ZnO hollow spheres wrapped by 2D g‐C 3 N 4 layers is fabricated. The electrostatic attraction between both components not only facilitates the exfoliation of g‐C 3 N 4 layers...
