▎ 摘 要
NOVELTY - Preparation of sulfur and nitrogen-co-doped graphene rich in edge defects, comprises using thiourea precursor and graphene oxide adsorption and hydrothermal self-assembly, preparing sulfur by chemical vapor deposition, nitrogen-Co-Doped graphene, grafted on the graphene edge by a coordination structure, and inducing the edge defect to generate, and providing a large number of active sites. USE - Preparation method of sulphur and nitrogen co-doped graphene rich in edge defect used in chemical industry, medicine and environment protection field for producing hydrogen peroxide. ADVANTAGE - The method has simple synthesis, high repeatability, and can be prepared in a large amount, and the precursor is cheap and easy to obtain. DESCRIPTION OF DRAWING(S) - The drawing shows an XRD pattern of SNC @ 800 prepared in Example 1. (Drawing includes non-English language text). Strong graphite (002)
