英文摘要The development of novel bifunctional electrocatalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is urgently desired for improving the efficiency of overall water splitting but remains a great challenge. Herein, a metal-organic frameworks (MOFs)-derived hybrid nanostructure consisted of multiple transition metal phosphide (NiCoZnP) nanoclusters and hierarchical ultrathin N-doped carbon (NC) nanosheets is successfully synthesized as binder-free bifunctional electrocatalysts for overall water splitting. The ultrafine and monodispersed NiCoZnP nanoclusters with uniform sizes of 3 nm are homogeneously distributed on the ultrathin NC nanosheets, leading to self-supported NiCoZnP/NC nanosheets array on carbon cloth (CC). The NiCoZnP/NC exhibits large surface area and numerous active sites due to the small sizes of NiCoZnP and hierarchical nanostructures of NC. Furthermore, the NiCoZnP/NC nanosheets are directly grown on CC and avoids the usage of binder, which significantly reduces the electrical contact resistance and exhibits superhydrophilic performance. Therefore, the self-supported NiCoZnP/NC nanosheets array demonstrates high HER activity with low overpotential of 74 mV and OER activity with overpotential of 228 mV to reach current density of 10 mA cm-2 in 1.0 M KOH solution, and exhibits remarkable overall water splitting performances with low potential of 1.54 V to drive 10 mA cm-2 and good long-term stability.
