Abstract
The invention provides a titanium carbide nanosheet/layered indium sulfide heterojunction and an application of the same in degrading and removing water pollutants. A simple electrostatic self-assembly method is used to uniformly absorb indium ions on the surfaces of Ti3C2 nanosheets, which effectively inhibits the stacking of the nanosheets and is beneficial to the uniform growth of In2S3 nanosheets on the surfaces of the Ti3C2. The present invent overcomes two disadvantages of too fast photogenerated carrier recombination rate of In2S3 and easy agglomeration of nano-scale In2S3, and effectively improves the separation efficiency and photocatalytic activity of photogenerated electron-hole of In2S3.
