Visible light response photocatalytic material and preparation and application thereof in micro-polluted water treatment

The invention provides a visible-light response photocatalytic material, preparation thereof and application of the visible-light response photocatalytic material in micro-polluted water treatment. The visible light response photocatalytic material is prepared by introducing graphene oxide into a carbon-doped g-C3N4 material to realize modification. According to the invention, a novel and stable graphene oxide modified carbon-doped g-C3N4 photocatalyst is synthesized, and the separation efficiency of carriers is obviously improved; through loading treatment, the photocatalyst is successfully attached to the surface of the carrier to form the supported catalyst, so that the recycling capability of the catalyst is effectively improved; the photocatalytic material has a high removal rate fororganic matters and ammonia nitrogen in micro-polluted water, and is beneficial to water environment restoration. 本发明提供一种可见光响应光催化材料及其制备与其在微污染水处理中的应用。所述可见光响应光催化材料通过将氧化石墨烯引入碳掺杂g-CN材料实现改性制得。本发明合成出一种新型、稳定的氧化石墨烯改性的碳掺杂g-CN光催化剂，明显增大
