Bimetallic nickel-iridium nanocatalysts for hydrogen generation by decomposition of hydrous hydrazine

Abstract

Alloying Ni with Ir leads to the formation of highly active catalysts for complete decomposition of hydrous hydrazine with 100% H(2) selectivity at room temperature. Use of surfactants enhances the activity by suppressing the agglomeration of nanoparticles, but does not affect the bimetallic compositions of the nanoparticles.
