Facile synthesis of porous 3D CoNiCu nano-network structure and their activity towards hydrogen evolution reaction

Nanostructured alloys have recently attracted great attention for hydrogen evolution due to their unique electron structure and large surface area. Herein, we reported a facile electrochemical method to prepare three-dimensional (3D) nano-network structures and demonstrated their feasibility as efficient electrocatalyst for hydrogen evolution. These 3D CoNiCu nano-network structure exhibited good performance in hydrogen evolution reaction (HER).

► A facile method has been developed to synthesize 3D CoNiCu nano-networks.
► The diameter of nanowires can be controlled between 5 and 7 nm
► Their compositions could be controlled by adjusting the deposition parameters.
► These 3D CoNiCu nano-networks show good performance in HER.
► The i0/Rf ratio is excellence while compared to other non-noble alloys.
