Titanium dioxide is the go-to material for a host of technological applications including self-cleaning glass, antifogging coatings, and ways to split water to make hydrogen fuel. To understand why TiO2 works well and possibly develop strategies to enhance its performance, researchers have now determined the first detailed mechanism of initial steps of oxidations catalyzed by TiO2’s less common mineral phase, anatase—reactions central to many TiO2 applications.

Most experimental surface studies have focused on the more . . .
