Effect of heat treatment temperature on the structural, morphological, optical and water contact angle properties of brookite TiO2 thin film deposited via green sol-gel route for photocatalytic activity

Brookite has only been utilized a few times and is always a by-product of TiO2. There have been few studies on the preparation of brookite coatings till recently with the existence of solvent. In this study, the structural, morphological, optical and water contact angle properties of brookite thin f...
