CDC was successfully synthesized via co-precipitation method using ammonium oxalate as a precipitating agent. CDC was characterized using Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), UV-Vis spectroscopy, and scanning electron microscopy (SEM). The band gap energy (Eg) of CDC was found to be 3.96 eV. In addition, the factors affecting the photodegradation of MG including; irradiation time, photocatalyst dosage, initial dye concentration, and solution temperature were studied. The results revealed that CDC could degrade approximately 93% of MG dye at the concentration of 6 mg/L, irradiation time of 90 min, photocatalyst dosage of 0.1 g, and solution temperature of 35 °C. The obtained results indicate that CDC is a promising material for the photocatalytic applications and can be used to eliminate very toxic dyes such as MG.}, keywords = {dye photodegradation,Nanostructured materials,doped ceria catalyst,Semiconductor,Optical properties}, url = {https://www.ajnanomat.com/article_92856.html}, eprint = {https://www.ajnanomat.com/article_92856_c405b04c2ab7e819ae6e1394a60febb2.pdf} } @article { author = {Pagar, Khanderao and Ghotekar, Suresh and Pagar, Trupti and Nikam, Amol and Pansambal, Shreyas and Oza, Rajeshwari and Sanap, Dnyaneshwar and Dabhane, Harshal}, title = {Antifungal activity of biosynthesized CuO nanoparticles using leaves extract of Moringa oleifera and their structural characterizations}, journal = {Asian Journal of Nanoscience and Materials}, volume = {3}, number = {1}, pages = {15-23}, year = {2020}, publisher = {Sami Publishing Company}, issn = {2645-775X}, eissn = {2588-669X}, doi = {10.26655/AJNANOMAT.2020.1.2}, abstract = {Copper oxide nanoparticles (CuONPs) were synthesized using Moringa oleifera leaf extract via a simple green chemistry approach.
