摘要: The ZnO/MgO solid samples containing the ZnO nanoparticles of controllable size were prepared using colloidal technique. The catalytic performance of the ZnO/MgO samples for the CO oxidation was measured. It was revealed that the rate of the CO oxidation reaction on the ZnO nanoparticles with variable average radius (2.01-2.29 nm) shows nonmonotonic dependence caused by the quantum-confinement effect.

Abstract: The effect of ZnO nanoparticle size on their catalytic activity in CO ox idation was studied. Nonmonotonic correlation between the CO oxidation rate and t he size of nanoparticles in a very narrow range of 2.0-2.3 n m was revealed.
