A Ti3+-rich rutile TiO2 with a surface lattice expansion structure was prepared by H-2 treatment. The supported Pt single atoms on this surface were stabilized in a highly oxidized state and had a weaker affinity for CO, resulting in robust catalytic performance.
A Ti3+-rich rutile TiO2 with a surface lattice expansion structure was constructed by H-2 treatment, on which the supported Pt single atoms were stabilized in a highly oxidized state under a CO oxidation reaction atmosphere and had a weaker affinity for CO, thus exhibiting robust catalytic performance.
