Abstract Greatly secure semiconducting materials of Ag doped ZrO2 (AZO) nanoparticles have been prepared by the use of hydrothermal and precipitation methods. Photocatalytic nanoparticles were characterized by UV-DRS, XRD, FT-IR and HR-SEM, HR-TEM, PL and CV techniques. Admirable improvement in the direct band gap of 4.61–4.58 eV was achieved as a result of doping. XRD diffraction pattern established the arrangement of monoclinic and tetragonal phase. The crystallite size and specific surface area were resoluted as 37.51 nm and 50.44 g/cm3. In addition, microscopic observation shows the Ag doped ZrO2 has achieved agglomeration and the particle diameter range between less than 100 nm of 5.81 and 7.65 1/nm. Luminescence and cyclic voltammetry are given additional supports towards optoelectronic characterization of Ag doped zirconium dioxide nanomaterials. The obtained ZO/AZO nanoparticles persist towards cationic dye of Rh6G at outfitted parameters of pH medium 9 implemented effectively in UV and solar light. The photodegradation of Rh6G dye is well described by pseudo-first order kinetics and high quantum yield. The Langmuir–Hinshel wood mechanism of photocatalytic effect of Ag doped Zirconium oxide nanomaterial have been discussed sucessfully and COD analysis was investigated. In this study, AZO material has to be proficient and potential remediated for contaminated water.

Introduction ZrO2 nanoparticles are wide bandgap of p-type semiconducting material that exhibit abundant energy consumption and oxygen vacancies on over its surface. Recently, zirconia has attraction towards catalytic field because of possessing high ion exchange and redox activity. It has technologically more uses in solid-oxide fuel cells, sensing applications of oxygen and nitrogen gas (Sudrajat and Babel 2016). Zirconia is a non-reactive ceramic materials, and it has wide range of applications in mechanical properties of physical–chemical methods (Kavitha et al. 2018). Silver noble metal is used as one of the best dopant for its great potential in thermal treatment, optical, electrical and surface catalytic improvement * S. Senthilvelan [email protected] 1

in nanofield. Noble metal of silver showed attractive singular properties of excellent conductivity, catalytic activity, bioactivity, chemical stability, anticancer, coating agent and bio-catalysis (Bumajdad et al. 2018). Doping of noble metal ions into ZrO2 is one of the best effective methods due to its propertie
