Problems solved by technology

Semiconductor oxides have relatively poor stability and low catalytic activity, and are still in the research and development stage; phthalocyanine and porphyrin macrocyclic conjugated complexes have good electrocatalytic activity due to their special macrocyclic conjugated structures. And it can be structurally adjustable by changing the substituent on its conjugated ring and the central metal atom and molecular aggregation mode, which endows it with a broad space for the development of electrocatalyst performance, and is one of the promising substitutes for platinum-based catalysts. One, but the preparation process of the catalyst is too complicated and there are many by-products

Description

technical field [0001] The invention relates to the field of material chemistry, in particular to a sulfaquinoxaline cobalt compound with electrocatalytic activity and a preparation method and application thereof. Background technique [0002] The electrocatalytic reaction is a catalytic reaction that accelerates the charge transfer at the electrode-electrolyte interface. Electrocatalysis covers two aspects of electrode reaction and catalysis, so electrocatalytic materials must have these two functions at the same time: (1) be able to transfer electrons freely; (2) be able to effectively catalyze the activation of substrates. Electrocatalytic reactions are mainly used in fuel cells, electrocatalytic treatment of organic sewage, electrocatalytic degradation of chromium-containing wastewater, electrolytic desulfurization of flue gas and raw coal, and simultaneous removal of NO by electrocatalysis x and SO 2 , Electrolytic reduction of carbon dioxide, electrolytic reduction o...
