As a promising candidate to replace Pt in hydrogen evolution reaction (HER), ruthenium phosphide catalysts have shown excellent performance and attract increasing attention. However, it is still a challenge to control the particle sizes of RuPxwere on the supports. In this study, the Schiff-based networks with 3D rigid organic networks are successfully grown on graphene, and the obtained composite was used as a new support for the RuPx. This composite can not only provide more metal coordinating sites but also restrict the growth of RuPx. Therefore, ultra-small RuPxnanoparticles are uniformly dispersedviaa subsequent phosphating and pyrolysis process. The final RuPx/NPG catalyst exhibits low overpotentials at the current density of 10 mA cm−2(32 mV in 0.5 M H2SO4solution, 13 mV in 1 M KOH solution, and 50 mV in 1 M PBS solution). This work provides a new strategy to solve the aggregation problem of the metal phosphides on the substrate by introducing Schiff-based networks into the graphene.
