RhP nanoparticles supported on reduced graphene oxide (RhP/rGO) synthesized by using a simple one-step wet-chemical approach have been investigated as superior catalysts toward dehydrogenation of hydrous hydrazine for chemical hydrogen storage. These RhP/rGO catalysts with different contents of P doping were characterized by ICP-AES, XRD, XPS, TEM, and STEM-HAADF. Thanks to the synergistic effect of phosphorous-doping, the obtained Rh92.6P7.4/rGO hybrid exhibits 100% H-2 selectivity, superior stability, and excellent catalytic performance with turnover frequency value (TOF) of 843.9 h(-1) toward hydrogen generation from alkaline solution of hydrazine at 323 K.
