Method for fabricating porous coated catalytic structures for coating multicomponent alloy for seawater hydrogen production

Abstract

A method for fabricating porous coated catalytic structures for seawater hydrogen production is disclosed. The method for fabricating porous coated catalytic structures for seawater hydrogen production comprises the following steps: utilizing a multicomponent alloy target material as the coating materials and a functional target as the co-sputtering material; conducting a pre-treatment process on the coating materials to generate a pre-treated substrate which has multiple surface dents; applying arc plasma technology to deposit a porous catalytic coating onto the pre-treated substrate, thereby forming a porous coated catalytic structure with coating multicomponent alloy; performing a post-treatment process for porous coated catalytic structure with coating multicomponent alloy; and assembling multiple porous coated catalytic structures with coating multicomponent alloy into hydrogen electrode sheets suitable for seawater electrolysis.
