BORON-SILICON CO-DOPED DIAMOND ELECTRODE, PREPARATION METHOD THEREFOR AND USE THEREOF

摘要

A boron-silicon co-doped diamond electrode, a preparation method therefor and use thereof. The boron-silicon co-doped diamond electrode comprises a substrate and a boron-silicon co-doped diamond layer provided on the substrate. The boron-silicon co-doped diamond electrode can effectively improve the conductivity of a diamond layer by doping boron element into the diamond layer, and can effectively improve the catalytic activity of the diamond layer by doping silicon element. Therefore, boron-silicon co-doping significantly increases the conductivity and catalytic activity of the diamond electrode, and in turn improves the production of ammonia gas through electrocatalytic nitrogen reduction. A preparation method for a boron-silicon co-doped diamond electrode can prepare a boron-silicon co-doped diamond electrode having excellent catalytic performance by means of simple processes, thereby simplifying preparation steps and reducing costs. Also disclosed are application examples where the boron-silicon co-doped diamond electrode is applied to electrocatalytic nitrogen reduction.
