Effect of alcohol solvents on TiO<inf>2</inf>films prepared by sol–gel method

© 2017 Elsevier B.V. The TiO2(anatase) films were prepared by sol-gel method using titanium (IV) isopropoxide (TTIP) as a precursor and polyvinylpyrrolidone (PVP) as a polymeric precursor dissolved in different alcohol solvents (methanol, ethanol, isopropanol and 1-butanol) and were heated treatment...
