Abstract: Hydrous hydrazine，N2H4?H2O，could be a promising hydrogen storage material due to its high hydrogen content (8.0wt%) and safe handling at mild conditions，with N2 as the only by-product. In this paper，the development of catalytic systems in hydrous hydrazine decomposition for H2 production was reviewed，including metallic nanoparticles，complex oxides，and supported catalysts. The mechanism of hydrazine decomposition was briefly introduced. The influencing factors for promoting H2 selectivity were discussed，including metal property，reaction conditions，and promoters. Also，the advantages and disadvantages of the reported catalysts were summarized，and performance development in hydrous hydrazine decomposition and other related reactions was also included.

Key words: hydrous hydrazine, hydrogen production, catalyst, selectivity
