This work investigated the suppression of photocatalytic activity of titanium dioxide (TiO2) pigment powders by extremely thin aluminum oxide (Al2O3) films deposited via an atomic-layer-deposition-type process using trimethylaluminum (TMA) and H2O as precursors. The deposition was performed on multiple grams of TiO2 powder at room temperature...

This work presents a novel chemical vapor deposition (CVD) approach that enables the deposition of ultrathin and conformal SiO<sub>2</sub> layers on TiO<sub>2</sub> anatase nanoparticles at room temperature using SiCl<sub>4</sub> and air containing water without the use of a catalyst. The morphology of the CVD-grown SiO<sub>2</sub> layers was...
