Abstract: Two-dimensional materials, which are the materials that can only move freely on non-nanometer scales of two dimensions, have become a hot topic in recent years due to its unique and excellent physical and chemical properties.The two-dimensional crystal MXene materials has good thermal conductivity, high thermal stability and oxidation resistance.The catalytic field shows great potential for degrading pollutants, hydrolyzing hydrogen, and reducing carbon dioxide.We introduce the structure of MXene and the preparation method of chemical liquid etching, high temperature decomposition and gas etching.The application of MXene in the field of photocatalysis was reviewed.The prospect and future research direction of MXene in photocatalysis are prospected.
