Abstract：
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.
摘要：
在这项研究中,以石墨烯气凝胶为载体合成了具有高光催化活性的光催化剂,水热法研究了镉掺杂TiO2复合材料对废水中有机染料的有效降解。这里,研究了GA-TiO2-Cd作为降解名为OrangeG的有毒染料的光催化剂，酸性蓝161和明亮的绿色在紫外光谱部分。作为实验的结果,据观察，有机染料的有效分解是由于石墨烯气凝胶（GA）和镉掺杂的TiO2纳米颗粒。结果表明，对于20ppm的橙G溶液，酸性蓝161和亮绿，染料的去除量约为81.075%，84.15%,和95.18%在120分钟。使用SEM-EDS确定合成复合材料的形态和元素分析，通过XRD进行晶体结构分析,通过FTIR进行化学键分析，紫外-可见-近红外分光光度法测定光学性质,和热阻通过TGA分析。
