Research progress on supported catalysts for hydrogen evolution from decomposition of hydrous hydrazine
Hydrogen has been widely concerned as a green energy source with high combustion energy release.Hydrazine hydrate(N2H4·H2O)is a hydrogen storage material with a high capacity of 8.0 wt.%,and holds great potential as a green hydrogen storage material since its decomposed product is safe and environmentally friendly.Catalyst plays a crucial role in the decomposition of hydrazine hydrate for hydrogen evolution.This re-view summarizes the effects of supported metal active center composition and carrier type on the catalytic effi-ciency,selectivity,and durability of supported catalysts for hydrogen generation through the decomposition of hydrazine hydrate.Different methods to improve the catalytic performance of these supported catalysts are ana-lyzed.Moreover,the article identifies the main issues and challenges in this research area and offers potential future development directions.
