Research Abstract

Titanium dioxide (TiO_2) has attracted great attention as the promising material for photocatalysts for environmental purification, functional coating, etc. In this work, we developed the methodologies for understanding the photocatalytic reaction mechanism of TiO_2 nano- and microcrystals and their composites with noble metal nanoparticles at the single-molecule, single-particle levels.
