Effect of dehydration rate on non-hydrolytic TiO2 thin film processing: Structure, optical and photocatalytic performance studies

► Clear transparent TiO2 thin film prepared using non aqua sol-gel processing. ► The complexing agents plays significant role in the rate of dehydration due to hydrolysis. ► Faster dehydration significantly affects visible light transmittance and other properties. ► Diethanoalamine plays significant role in the crystallization and phase transformation.
