Education:•Ph.D.(Materials Science & Nanomaterials) Thesis Title: “Preparation, Characterization and Spectral studies of Pyrochlores and Tungstates”•Research Supervisor: Prof. M. Vithal (Material Chemistry), Department of Chemistry, Osmania University, Hyderabad, India.•M. Sc.(Master of Science) in Physical Chemistry, Department of Chemistry, Osmania University, Hyderabad, India.•B. Sc.(M.P.C)(Bachelor of Science), Osmania University, Hyderabad, India.Summary:•Over 16+ year’s experience in an Academic & Scientific Research Organizations.•Good exposure in Material & Nanomaterials Synthesis.Research Experience:Gained experience in the synthesis of pyrochlore type compounds, tungstates and NASICON type compounds by citrate sol-gel method.Gained experience in the basic characterization techniques such as powder XRD, FT-IR, Raman spectroscopy, XPES, ESR, TEM, SEM, EDS, DRS, ICP-AES, absorption and emission (photoluminescence).DC conductivity (by two probe method) measurements as a function of temperature and photocatalytic activity for YLnTi2O7 (Ln = Nd, Sm, Eu and Gd) were carried out.The Photocatalytic activity and AC Conductivity studies of pyrochlore type YLnTiZrO7 (Ln = La, Nd, Sm and Eu) were carried outEffect of crystallite size on electron resonance of Gd3+ and luminescence of Eu3+ Doped in La6WO12 (Rare earth tungstate) has been studiedUsed Rietveld refinement for structural refinement of crystalline materials.Synthesis of oxide materials such as Ta2O5, Nb2O5 using pressure cooker experiment. Synthesis of mesoporous materials namely SBA-15 by hydrothermal method.Preparation of pyrophosphates and borates by solid state metathesis reactionsCurrent ResearchPhotocatalysis is a green technology for the treatment of all kinds of contaminants, especially for the removal of organic contaminants with solar energy, which mainly includes oxidative decomposition of the Volatile Organic Compounds (VOC), hydrogen production, effluents detoxification and disinfection. Development of semiconducting materials for the photolysis of water to produce hydrogen and for the decomposition of harmful organic contaminants has grown into an interesting area of research in both science and engineering fields. So I would like to investigate the photocatalytic activities of Ag+/ Cu2+/ Sn2+-doped ABi2M5O16 (A = K, Ag, Cu and Sn; M = Sb, Nb and Ta) materials and the influences of doping effect on the photocatalytic properties of these compounds under both ultraviolet and visible light (λ > 400 nm) irradiation
