Nano-flocks of a bimetallic organic framework for efficient hydrogen evolution electrocatalysis

Nano-flocks of a bimetallic organic framework (NiCo-MOF) were grown on a nickel mesh and covered with a graphene oxide aerosol skeleton by employing a nebulizer air compressor. The resulting material induces a high accessible active surface area and shows enhanced electrocatalytic activity towards the hydrogen evolution reaction with excellent stability in alkaline medium.
