Inert V2O3 oxide promotes the electrocatalytic activity of Ni metal for alkaline hydrogen evolution†
Abstract
Here, we develop inert V2O3 oxide to enhance the HER activity of industrial Ni catalysts with the assistance of abundant metal/oxide interfaces. The as-synthesized Ni/V2O3 catalyst exhibits over 5 times the activity of a pure Ni sample due to the particle size control and metal/oxide interaction, and excellent durability as a result of oxide anchoring.
