%X In this study, photocatalysts with high photocatalytic activity performance are synthesized by synthesizing graphene aerogel-supported, cadmium-doped TiO2 composites by hydrothermal method for the effective degradation of organic dyes in wastewater. Here, GA-TiO2-Cd is investigated as a photocatalyst for the degradation of toxic dyes named Orange G, Acid Blue 161, and Brilliant Green in the UV part of the light spectrum. As a result of the experiments, it is observed that the effective decomposition of organic dyes is due to graphene aerogel (GA) and cadmium-doped TiO2 nanoparticles. The results show that for 20 ppm solutions of Orange G, Acid Blue 161, and Brilliant Green, dyes are removed at approximately 81.075%, 84.15%, and 95.18% in 120 min. The morphology and elemental analysis of the synthesized composites are determined using SEM-EDS, crystal structure analysis by XRD, chemical bond analysis by FTIR, optical properties by UV-Vis-NIR spectrophotometry, and thermal resistance by TGA analysis.
