Noble-metal-free NiFeMo nanocatalyst for hydrogen generation from the decomposition of hydrous hydrazine

Noble-metal-free NiFeMo nanoparticles without any surfactant or support have been facilely synthesized and successfully applied as a highly efficient catalyst for the rapid and complete decomposition of hydrous hydrazine (a promising hydrogen storage/generation material) for hydrogen generation at a mild temperature. The surfactant/support-free nanoparticles possess good dispersion and small particle size. Moreover, upon the incorporation of Mo and Fe, the catalytic activity and hydrogen selectivity of the present trimetallic catalyst are remarkably improved compared with its mono-/bi-metallic counterparts.
