Abstract
A modification method of an anode for hydrogen production via electrolysis, the anode for hydrogen production via electrolysis and use thereof are provided. The modification method of the anode for hydrogen production via electrolysis includes providing an anode substrate which can be used for hydrogen production via catalytic electrolysis; and depositing a plurality of silver nano particles on the active surface of the anode substrate to form a silver nano layer, wherein gaps are present between the silver nano particles, and a part of the active surface is exposed from the gaps. In the modification method provided by the present application, the silver nano layer covers on the surface of the anode substrate, and chlorine ions are adsorbed onto the surface of silver in the process of hydrogen production via electrolysis to form a chlorine removal layer.
