Abstract

Hollow structures with hierarchical architecture and multi-composition have attracted extensive interest because of their fascinating physicochemical properties as well as wide applications. to improve the efficiency of overall water splitting, highly active and stable electrocatalysts are highly desirable. A novel high-efficiency Hierarchical hollow nanosheet-based-nanosphere Co-NiMoO4-HNS electrocatalyst for oxygen evolution was arranged by doping Co on Ni-MoEG yolk/shelll nanosphere. Remarkably, the hierarchical hollow Co2-NiMoO4-HNS catalyst exhibits favorable catalytic performance toward the oxygen evolution reaction (OER) with a receivable overpotential of 270 mV achieving a current density of 10 mA cm−2 and a Tafel slope of 65 mV dec−1. In expansion, as a electrocatalyst, Co2-NiMo4-HNS appeared to have great long-term steadiness in the electrolyte. This work may give broad hypothetical and specialized back for the plan of cost-effective bifunctional electrocatalysts.
