Facile synthesis of P-doped Rh nanoparticles with superior catalytic activity toward dehydrogenation of hydrous hydrazine

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 Rh 92.6 P 7.4 /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.
