A sulfur-doped graphitic-like carbon nitride nanosheet supported graphene and ferric oxide composite magnetic photocatalyst, which uses a sulfur-doped graphitic-like carbon nitride nanosheet as a carrier, and the sulfur-doped graphite-like nanosheet is used as a carrier. The carbon nitride nanosheets are decorated with graphene and ferric oxide particles. The preparation method comprises the following steps: using thiourea high temperature pyrolysis to prepare sulfur-doped graphitic carbon nitride nanosheets; Doped graphitic-like carbon nitride supported graphene and ferric oxide composite photocatalyst material. The composite magnetic photocatalyst of the invention has the advantages of high photocatalytic activity, good stability, easy recovery by magnetic force, simple operation, low cost and good safety in the preparation process. The composite magnetic photocatalyst of the invention can be used for treating wastewater containing various antibiotics and medicines, and has good stability and practicability, high efficiency, simple operation, low cost, and high value of recycling and reuse. |
