| 摘要 |
Disclosed herein is a catalytic assembly comprising a porous electrically conductive substrate, and a porous metallic composite coating the substrate, where the catalytic assembly has a three dimensional interpenetrating porous structure, where the substrate has a three dimensional interpenetrating porous structure having a first average pore diameter (PD SUB ), and the porous metallic composite is amorphous and has a three dimensional interpenetrating porous structure having a second average pore diameter (PD PMC ), the PD PMC being sufficiently smaller than the PD SUB to allow the porous metallic composite to coat substrate surfaces throughout the substrate including surfaces of pores in the substrate. The catalytic assembly may be suitable for use as oxygen evolution reaction (OER) catalysts and hydrogen evolution reaction (HER) catalysts, among others. |
