2D S-Scheme Heterojunction Photocatalyst

二维S型异质结光催化剂

The application of photocatalytic technology in H_(2) production,CO_(2) reduction,H_(2)O_(2) production,and pollutant degradation provides a promising approach to the alleviation of energy shortage and environmental issues 1-3.However,hindered by the easy recombination of electron-hole pairs,single-component photocatalysts usually exhibit inferior performance.Constructing heterojunction photocatalysts is a valid method which can improve charge separation and attain high catalytic efficiencies4.
