The invention relates to the field of electrocatalytic materials, in particular to an anion modified NiCo hydroxide electrocatalytic material and application thereof. The NiCo hydroxide modified by phosphate radicals and other anions is synthesized through a two-step hydrothermal method, and the performance of the NiCo hydroxide for preparing amide through electro-catalysis ethanolamine oxidative coupling is studied.
