Interfacial Electric Fields and Chemical Bonds in Ti3C2O-Crafted AgI/MoS2 Direct Z-Scheme Heterojunction Synergistically Expedite Photocatalytic Performance
The photocatalytic performance of heterojunctions is often restricted by inferior contact interface and low charge transfer efficiency. In this work, Ti3C2O MXene was crafted with AgI/MoS2 to produce a Z-scheme heterojunction (AgI/MoS2/Ti3C2O). Interfacial electric fields and chemical bonds were proven to exist in the heterojunction. The interfacial electric fields supplied a powerful driving force, and the interfacial Ti-O-Mo bonds served as an atomic-level channel for synergistically expediting the vectorial transfer of photogenerated carriers. As a result, AgI/MoS2/Ti3C2O exhibited significantly improved photocatalytic activity, demonstrating a high H2O2 production rate of 700 μmol·g−1·h−1 and a rapid degradation of organic pollutants.
