Atomically thick Ni(OH)2 nanomeshes for urea electrooxidation

Atomically thick two-dimensional Ni(OH)₂ nanomeshes with 1.7 nm thickness and numerous nanoholes are handily achieved by a simple NaBH₄ assisted cyanogel hydrolysis method, which show outstanding electrocatalytic activity for the urea oxidation reaction in the alkaline electrolyte.
