The use of graphite carbon nitride carbon bismuth molybdate modified, thereby significantly improving the photocatalytic efficiency. X-ray diffraction analysis, scanning electron microscopy and UV-Vis spectrophotometer were used to systematically understand the influence of the structure of bismuth molybdate catalyzed by graphitic carbonitride on its visible light catalytic properties. By analyzing the nature of the electronic interaction between the graphite carbonitride carbon surface modification material and the bismuth molybdate photocatalytic material and the influence on the photogenerated charge transfer, the graphite phase nitrided carbon hybrid with the conjugated π bond system can At the interface of bismuth molybdate, an electron interaction is formed to promote the transport and separation of photogenerated carriers, and the surface state and mechanism of carbon nitride and bismuth molybdate nanosheet surface are revealed.
