$ V_{2} $$ O_{4} $ Nanowires/rGO Hybrid for Electrocatalytic Nitrogen Fixation
$ NH_{3} $ plays an important role in the agroindustry, but its existing preparation processes generate a lot of pollution, which is not conducive to sustainable development. Electrochemical nitrogen reduction is a clean process for preparing ammonia, it relies on a catalyst with excellent performance. Here, we studied a vanadium tetroxide nanowire electrocatalyst supported on reduced graphene oxide, which has excellent performance in the production of $ NH_{3} $. In the 0.1 mol $ L^{−1} $ $ Na_{2} $$ SO_{4} $ electrolyte, the highest $ NH_{3} $ yield of catalyst achieved 24.75 μg $ h^{−1} $·$ mg_{cat.} $−1 at − 0.3 V (V vs. RHE) potential, and the Faraday efficiency was up to 79% at − 0.2 V (V vs. RHE). This study provides a basis for subsequent improvement of catalyst performance. Graphical Abstract.
