Photocatalytic hydrogen evolution is an efficient strategy to convert solar energy into hydrogen energy, which is of significant importance to solve the issues of energies shortage and environmental pollution. Transition metal sulfides have been widely investigated owing to their high catalytic activity, appropriate band gap, and wide range of photo responsive capacity and low cost. At the same time, benefiting from their adjustable structure, high specific surface area and diverse metal centers, metal-organic frameworks (MOFs) are promising precursors to prepare transition metal sulfides. In this paper, recent progress of transition metal sulfide photocatalytic materials derived from MOFs for hydrogen evolution are summarized. The effects of metal centers, nanostructure and band gap of the metal sulfides on their photocatalytic hydrogen evolution efficiency are discussed and the proposed reaction mechanisms are summarized. In addition, the challenges and development direction in this area are proposed to provide new guidance for the progress of MOFs-derived metal sulfides photocatalysts.
