Nitrogen and sulfur co-doped porous carbon microsphere, preparation method and application thereof and oxidization-reduction electrode

Abstract

The invention relates to a preparation method of a nitrogen and sulfur co-doped porous carbon microsphere composite material. The method comprises the following steps of S1, performing closed reactionon hexachlorobutadiene, tellurium diethyl dithiocarbamate (TDEC) and a solvent under high temperature and high pressure; S2, relieving pressure to normal pressure after reaction is completed, naturally cooling to a room temperature, and drying the obtained solid to obtain a dried sample; and S3, performing high-temperature roasting processing on the dried sample under protection of inert gas so as to obtain the nitrogen and sulfur co-doped porous carbon microsphere composite material. The invention also relates to the composite material, application thereof and oxidization-reduction performance comprising the composite material. The nitrogen and sulfur co-doped porous carbon microsphere composite material has excellent performance and can be used for preparing an oxidization-reduction electrode of a fuel cell, so that the nitrogen and sulfur co-doped porous carbon microsphere composite material can be used in the fuel cell, shows excellent electrochemical performance and has huge application potential and industrial value in the field of electrochemistry.

Description

Technical field [0001] The present invention provides a composite material, a preparation method, application thereof, and an electrode prepared therefrom. More specifically, a composite material, a preparation method, application and an electrode prepared therefrom are provided. The reduction electrode belongs to the technical field of inorganic functional materials and electrochemical energy. Background technique [0002] At present, traditional energy sources (such as natural gas, oil, and coal) are increasingly depleted and have serious environmental pollution. There is an urgent need to develop green and renewable energy sources. As a clean energy conversion device, the fuel cell has a high energy conversion rate and is safe, so it has attracted the attention of scientific researchers. The most commonly used fuel cell catalyst is a platinum-based catalyst. However, due to the high price of platinum and lack of resources, the cost of the catalyst is high. At the same time,...
