Patent number: 11833491Abstract: 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.Type: GrantFiled: July 18, 2022Date of Patent: December 5, 2023Assignee: Suzhou University of Science and TechnologyInventors: Chengbao Liu, Fei Tang, Tao Jin, Feng Chen, Junchao Qian, Zhigang Chen
