CeOx-modified NiFe nanodendrits grown on rGO for efficient catalytic hydrogen generation from alkaline solution of hydrazine

CeOx-modified NiFe catalysts with branched nanodendritic architectures have been successfully deposited on reduced graphene oxide (rGO) through a simple co-reduction method. Thanks to the synergistic electronic effect between Ni, Fe, and Ce, as well as dendritic morphology with a high number of active sites, the resulted Ni3Fe-(CeOx)0.15/rGO exhibited superior catalytic activity toward dehydrogenation of hydrous hydrazine in alkaline condition, with turnover frequency (TOF) values of 56.8 h−1, and 126.2 h−1 at 328, and 343 K, respectively.
