Abstract
Abstract The switch of CO 2 hydrogenation selectivity from CH 4 to CO over TiO 2 supported Rh catalysts is accomplished via selective encapsulation of Rh nanoparticles while exposing Rh single atoms by high‐temperature reduction (HTR) according to their different strong metal‐support interaction (SMSI) occurrence conditions, which can be reversed by subsequent oxidation treatment.
