Heterostructure Co3O4@NiWO4 nanocone arrays with enriched active area for efficient hydrogen evolution reaction
Source abstract
Abstract
Abstract Low cost and efficient electrocatalysts are extremely attractive for hydrogen evolution reaction (HER). Here, three-dimensional hybrid Co3O4@NiWO4 nanocone arrays are firstly constructed by a simple and effective strategy on nickel foam. Due to the open space and enriched active areas provided by the special nanocone arrays heterostructure, Co3O4@NiWO4 exhibits excellent HER performance. The overpotential is only 70 mV at 10 mA cm−2, and it also has good durability under alkaline conditions. This research provides a guiding strategy for the synthesis of high-efficiency and stable electrocatalyst for the HER by enriched active areas.
