Novel silver-doped CdMoO_4: synthesis, characterization, and its photocatalytic performance for methyl orange degradation through the sonochemical method

摘要

A novel silver-doped tetragonal phase of cadmium molybdate nanoparticles (Ag°-CdMoO_4) were successfully synthesized through the sonochemical method. The effect of processing parameters such as the dosage of sucrose and ultrasonic power on the morphology and particle size was investigated. Furthermore, sucrose was applied as a green capping agent. The sample indicated a ferromagnetic behavior, as evidenced by using vibrating sample magnetometer (VSM) at room temperature. The SEM results revealed that the morphology of CdMoO_4 nanoparticles is highly dependent on the reaction conditions. Photocatalytic activities of the Ag°-CdMoO_4 samples were evaluated by the degradation of methyl orange dye under visible light irradiation. It has been observed that the sample containing 0.5 mol of Ag showed the best photocatalytic activity as compared to other samples. The nanoparticles structure has been elucidated by XRD, SEM, UV-Vis, EDX, VSM, and FTIR.
