NiFeRuOx nanosheets on Ni foam as an electrocatalyst for efficient overall alkaline seawater splitting
The electrocatalyst NiFeRuOx/NF, comprised of NiFeRuOx nanosheets grown on Ni foam, was synthesized using a hydrothermal process followed by thermal annealing. NiFeRuOx/NF displays high electrocatalytic activity and stability for overall alkaline seawater splitting: 98 mV@ 10 mA∙cm−2 in hydrogen evolution reaction, 318 mV@ 50 mA∙cm−2 in oxygen evolution reaction, and a cell voltage of 1.53 V@ 10 mA∙cm−2, as well as 20 h of durability. A solar-driven system containing such a bifunctional NiFeRuOx/NF has an almost 100% Faradaic efficiency. The NiFeRuOx coating around Ni foam is an anti-corrosion layer and also a critical factor for enhancement of bifunctional performances.
