Advanced Energy and Sustainability Research, EarlyView.In this article, the preparation of a three‐dimensional nanoflower Mn‐ doped NiC/NiO electrocatalyst, which exhibits excellent catalytic activity in the hydrogen evolution reaction. The doping of Mn not only modulates the morphology of the electrocatalyst but also provides electrons to the Ni sites of NiC/NiO, which effect promotes the desorption of H2.
