The current state of research on photocatalytic systems for hydrogen production by metal carbides is considered. Approaches for obtaining of known and latest two-dimensional metal carbides (MXenes) and their composites with the participation of photoactive semiconductors or organic dyes are described. Properties of these materials such as photocatalysts, and precursors used in their obtaining or co-catalysts used in hydrogen production systems where metal carbides act as acceptors and carriers of photogenerated charges or catalysts of the hydrogen evolution reaction are analyzed. The most promising areas of further research are outlined.
