Description

technical field

[0001] The invention relates to the field of preparation of catalytic materials, in particular to a multi-level structure material in which boron-doped cobalt hydroxide is loaded on a porous copper substrate and a preparation method thereof. Background technique

[0002] Cobalt is a common electrocatalytic material, especially two-dimensional cobalt and cobalt hydroxide nanosheets in catalytic / electrocatalytic NaBH 4 , N 2 h 4 , NH 3 -BH 3 Hydrogenolysis and electrolysis of water for hydrogen evolution and oxygen evolution have high catalytic performance, and boration can further improve the catalytic activity. Patent 201610815684.X discloses a flaky porous cobalt boride powder and its preparation method, the powder is Co boride with an average thickness of 20nm x The B (x=1, 2, 3, 4) nanosheets are formed by interconnecting each other. The literature (CoB / Cu and PtCoB / Cucatalysts for borohydride fuel cells. Electrochimica Acta 2017, 225, 255-262.) repo...
