Surface Ir-Ti Alloy Formed via Strong Metal − Support Interaction over Ir/TiO2

The strong metal-support interaction and its chemical nature was examined over a Ir/TiO 2 catalyst, constructed by dispersing 2 nm Ir colloids on the {001} facets of anatase TiO 2 . Air-calcination of the Ir/TiO 2 sample led to the oxidation of Ir particles into IrO x clusters. Upon H 2 -reduction a...
