investigation of photocatalytic activity of nd-doped zno nanoparticles using brilliant green dye: synthesis and characterization

An nd doped zno (1-5%) photocatalyst was successfully synthesized via chemical co-precipitation method. the optical property, nature, and morphology of the synthesized nanoparticles were analyzed by uv-visible, xrd, and fesem respectively. xrd study reveals that nd has been effectively incorporated in the zno lattice in the lower level dosage; however the crystalline nature has been distorted towards the increase in the nd. the selected brilliant green dye was degraded photo-catalytically with the help of the synthesized nanoparticles and the study has been extended with catalyst dosage and dye concentration. the 2% nd-doped zno showed a remarkable result of 98.26% degradation of brilliant green dye compared to the other 1,3,4 & 5 % nddoped zno nanoparticles which clearly indicates the optimization of depletion region corresponding to the maximum degradation. the increased content (3-5%) of nd-doped zno exhibited moderate photocatalytic degradation of the dye due to the decreased crystalline nature which was further evidenced from xrd studies.
