| Abstract: | Taking TaiXi anthracite as the presoma, prepared coal-based graphene by catalyzing graphite and oxidating reduction method, studied its application in carbon dioxide photocatalytic process, mainly researched the effects of ferric sulfate and boric acid on the anthracite graphitization process, and the key technology of the preparation of coal-based graphene by the improved Hummers method which coupled plasma to resist the electro-discharge.The results showed that under the effect of Boron / Fe composite catalyst, it could achieve the graphitization of anthracite; and could prepare the coal-based graphene which achieve good micromeehanism based on the graphite products; in the progress of photo- catalytic conversion of CO2, when the illumination time is 14h, the added amount of coal-based graphene was lg/L, the flow of C02 was200ml/min, the target product of methanol could be 144.19μmol/L. |
