Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.
