Study structure characteristics and the photocatalytic degradation of Rhodamine B on C/g-C3N4 composites

C/g-C3N4 composites were successfully synthesized by calcination method from precursors g-C3N4 (CN) with carbon from orange peel (OC). The products were characterized by physicochemical methods such as XRD, IR, SEM, BET, UV-Vis. The photocatalytic activity of the material was evaluated through the degradation of RhB in the visible light. Experimental results show that the OC/CN-150 composite exhibits the optimal catalytic activity of 90% after 1 hour of illumination. This study highlights the role of carbon synthesized from biomass sources. Besides, it can be combined with other materials to create composites to apply for photocatalysis to solve environmental problems.
