Curvature-induced reaction pathway switching of CO oxidation on Pt1/Pt2 anchored CeO2 nanotubes: a first-principles study.

sites optimize the electronic structure of the catalysts through charge recombination, the small-diameter single-atom system exhibits prominent advantages owing to its unique coordination environment. This work establishes a new mechanism of curvature-induced reaction path switching, and provides solid theoretical guidance for the rational design of high-efficiency CO oxidation catalysts.
