Abstract

Atomically dispersed Pt catalysts are synthesized on TiO₂ with high activity and strong high temperature resistance by loading Pt in the process of converting the NH₄TiOF₃ precursor to TiO₂ by a topotactic transformation process. The atomically dispersed Pt catalyst displayed high catalytic activity for the low temperature CO oxidation reaction.
