Abstract

See full text

The invention provides a sulfur doping method for graphene, which comprises the steps of: 1) providing graphene and placing the grapheme in a chemical vapor deposition reaction chamber; 2) employing an inert gas to perform ventilation and exhaust treatment in the reaction chamber; 3) introducing a sulfur source gas to perform sulfur doping on the graphene at 500-1050° C.; and 4) cooling the reaction chamber in a hydrogen and inert gas atmosphere. The present invention can perform sulfur doping on the graphene simply and efficiently, the economic cost is low, and large-scale production can be realized. Large area sulfur doping on graphene can be realized, and doping of graphene on an insulating substrate or metal substrate can be carried out directly.
