2016年4月1日 · This work studies the effect of Cu doping on structural, morphological, optical, dielectric and photocatalytic activity of TiO2 nanoparticles. Pure and Cu doped TiO2 nanoparticles were synthesized using sol–gel technique.

2022年10月25日 · Light-harvesting of titanium oxide (TiO 2) was enhanced by copper (Cu) doping, and its performance was evaluated by gabapentin (GBP) degradation under UVA-LED irradiation. The morphology and structure of TiO 2 and Cu-TiO 2 were characterized using XRD, FTIR, FE-SEM, EDX, TEM, PL, DRS, and BET analysis.

The present work reports the synthesis of undoped and transition metal (Cu and Ni) doped CdS nanoparticles. The synthesis of pure and doped CdS nanoparticles have been carried out in aqueous medium by microwave assisted solvo thermal method using cadmium acetate, nickel chloride, copper chloride and sodium sulphide as precursors.
