摘要：

A facile and efficient electrocatalyst for hydrogen evolution reaction (HER) to produce hydrogen is very important for future energy. In this paper, amorphous manganese-cobalt nanosheets are successfully prepared by electrospinning on a foamed nickel substrate. It is found that the manganese (Mn) introduction in manganese-cobalt composites can simultaneously enhance their electrocatalytic performances. As a result, benefitting from the 3D structure, the self-supported Mn-Co hydroxides exhibits unprecedented HER activity with a relatively low overpotential of 100 mV at 10 mA cm(-2) and has a possibility for the large-scale production of hydrogen.
