One stone two birds: Vanadium doping as dual roles in self-reduced Pt clusters and accelerated water splitting

Vanadium dopant into NiFe LDH nanosheets can not only favor mild self-reduction of Pt ions into clusters, but also boost the water-splitting kinetics of the resulting Pt/NiFeV LDH nanocomposites via regulating the interfacial electron redistribution. This work can spark inspiration of designing other bifunctional electrocatalysts toward efficient energy conversion and storage.
