V-Doping coupled H2O2 pre-oxidation synergistically promote NiCo-LDH for urea oxidation-assisted hydrogen production

A NiCoV layered double hydroxide (LDH) nanosheet array structure grown on reduced graphene oxide (rGO) uniformly modified Ni foam was synthesized through V-doping coupled H 2 O 2 pre-oxidation using a hydrothermal method.
