S-Scheme Heterojunction Formed by Mo-Doped ZnIn<sub>2</sub>S<sub>4</sub> Nanosheets and SrTiO<sub>3</sub> Nanorods as Catalyst for Formaldehyde Degradation under Visible Light
The utilization of solar energy for pollutants removal is of critical importance for future society developments. In this paper, photocatalysts (Mo-ZIS/STO) compositing Mo-modified ZnIn2S4 (ZIS) nanosheets with SrTiO3 (STO) nanorods are prepared by electrostatic spinning. Mo dopant in S-scheme heterojunction widens the available spectral range and enhanced interfacial electric field effect (IEF), Mo0.05-ZIS/STO catalyst achieved 73.1% formaldehyde removal within 1 h. The intermediates produced during the removal of formaldehyde were characterized using in-situ DRIFTS. This work offers a perspective on the construction of photocatalytic field with metal doping and S-scheme heterojunctions, with the aim of enhancing photocatalytic performance.
