Recent Advances in MnxCd1−xS Solid‐Solution‐Based Photocatalysts for Preparation, Modification, and Application

In recent decades, MnxCd1−xS‐based photocatalysts have attracted much attention in the photocatalytic hydrogen evolution, reduction of CO2, and degradation of pollutants by virtue of their large visible‐light response range and high photogenerated electron mobility efficiency. This paper provides a systematic and comprehensive account of the synthesis, modification, and application of MnxCd1−xS‐based solid solution photocatalysts. Specifically, several common preparation methods of MnxCd1−xS, such as hydrothermal, solvent‐thermal, and high‐temperature vulcanization are outlined in terms of synthesis. It is also detailed that the photocatalytic performance of MnxCd1−xS can be well improved by elemental doping, morphology modulation, construction of heterojunction, and addition of cocatalysts. Furthermore, the current challenges and development of MnxCd1−xS‐based photocatalysts are proposed. It is of great significance for subsequent researchers to prepare efficient and stable MnxCd1−xS‐based photocatalysts in future.
