Unlocking the potential of a NiMo foam substrate for water splitting using an ultrafast two-step dipping strategy

Abstract

In this paper, a facile and ultrafast two-step dipping process was developed to in situ form an electrocatalyst on a NiMo foam substrate without consuming extra energy. The obtained electrode showed a porous coral-like structure decorated with nanosheets and exhibited excellent overall water splitting properties in alkaline solution. This study provides a feasible strategy for developing an environmentally friendly and energy-efficient non-noble metal electrode for hydrogen production from water splitting.
