摘要

The electrodeposited nickel and cobalt films are directly phosphorized in alkaline hypophosphite solution under the action of electric current. After the electro-phosphorization process, the morphology of nickel and cobalt films change obviously, and phosphorus element can be detected in the phosphorized films according to the EDS and XPS tests. The electrocatalytic performance of nickel and cobalt films for hydrogen evolution reaction are obviously enhanced by the electro-phosphorization treatment. Especially, the phosphorized nickel film has an overpotential of 57 mV at the current density of 10 mA.cm(-2).
