Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

open access: yesResponsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...
