Abstract: The present disclosure provides a synthesis method of a g-C3N4/C composite material based on a hollyhock stalk, including the following steps: (1) pretreatment of hollyhock stalks; and (2) fabrication of the g-C3N4/C composite material. In this method, with the hollyhock stalk as a carbon skeleton, g-C3N4 is spread on a template surface to form a laminated layer, and a composite system with a special structure is constructed. Compared with pure phase g-C3N4, the composite material substantially increases specific surface area and has a clear interface; the carbon skeleton not only functions as a rigid support, but also increases the electron transfer efficiency of the composite material, thereby improving the separation efficiency of photogenerated carriers and the utilization rate of visible light. Raw materials used in the method are inexpensive and environmentally friendly, which can be used for industrial production and bulk production of eco-friendly materials for harnessing environmental organic pollutants.
