Activating Inert Sites in Cobalt Silicate Hydroxides for Oxygen Evolution through Atomically Doping
2021
Energy & Environmental Materials
Metal silicate hydroxides have been recognized as efficient oxygen evolution reaction (OER) electrocatalysts, yet tailoring of their intrinsic activity remains confused. Herein, Fe had been incorporated into cobalt silicate hydroxide nanosheets and the resulted material achieves a competitive OER catalytic activity. It is found that the doping state obviously affects the electrical transport property. Specifically, highly dispersed Fe atoms (low-concentration Fe doping) trigger slight electron
