Abstract
Abstract Rational design of the catalysts is impressive for sustainable energy conversion. However, there is a grand challenge to engineer active sites at the interface. Herein, hierarchical transition bimetal oxides/sulfides heterostructure arrays interacting two-dimensional MoO x /MoS 2 nanosheets attached to one-dimensional NiO x /Ni 3 S 2 nanorods were fabricated by oxidation/hydrogenation-induced surface reconfiguration strategy. The NiMoO x /NiMoS heterostructure array exhibits the overpotentials of 38 mV for hydrogen evolution and 186 mV for oxygen evolution at 10 mA cm −2 , even surviving at a large current density of 500 mA cm −2 with long-term stability. Due to optimized adsorption energies and…
