A co-precipitation technique was employed for the preparation of ZnO doped dysprosium oxide from the respectivemetal nitrates and characterization studies were conductedby FT-IR, X-Ray Differaction, UV-Visible-DRS and FE-SEM analysis. XRD showed the prepared nanomaterial to be in a nano range with high crystallinity. The particles possesed a spherical morphology and of the order of 40-50 nm(particle size) as evidenced from FE-SEM analysis. From theUV-Visible-DRS analysis the band gap energy was calculated as 3.15 eV. The synthesizedZnO doped dysprosium oxide was employed as a photocatalyst under UV light irradiation for selective organic transformation reaction. Quinones especially benzoquinones are a class of compounds which forms a basic structural skeleton for various natural compounds. They are widely employed asa precursor for natural products synthesis. Herein we report the synthesis of N-phenyl-p-benzoquinonimine from diphenylamine by employing ZnO doped dysprosium oxide as a photocatalyst under UV light irradiation in ethanol. Thin Layer Chromatography was used to check the progress of the reaction. Optimization studies for the reaction parameters were conducted systematically.}, keywords = {Diphenylamine,lanthanide oxide,n-phenyl-p-benzoquinonimine,photocatalysis,selective organic transformation UV irradiation,Zinc oxide}, url = {https://amp.iaamonline.org/article_16068.html}, eprint = {https://amp.iaamonline.org/article_16068_e7dcb90bf3e1bcb9c4346e56204167fd.pdf} }
