摘要：

The present report describes the synthesis and characterization of TiO2 thin film semiconductor using titanium isopropoxide dispersed in different solvents like ethylene glycol (EG), glycerol, acetonitrile, dimethyl formamide, dimethyl sulphoxide and water followed by annealing at 600(0) C in air on the In-doped tin oxide (ITO) coated glass. UV-vis absorption spectrum measures the band gap energy 3.1 eV, indicating UV absorptivity of the materials, whereas XRD analysis reveals preferential growth of anatase form of TiO2 with tetragonal body-centred cubic lattice. The material developed from EG recorded the highest photoelectrochemical water oxidation current similar to 400 mu A cm(-2) at 0.8 V vs. Ag/AgCl, with 17% incident photon to current conversion efficiency (IPCE) and similar to 22% absorbed photon to current conversion efficiency (APCE).
