Copper and Nickel Selectively Deposited on Hybrid Ceria-Alumina Nanoparticles as Catalysts for CO Oxidation
Source abstract
Abstract
The strategy of accurately introducing multiple components into a catalytic system is an important issue for the development of high-efficiency catalysts. The regionally selective deposition of copper–nickel over hybrid ceria-alumina is investigated experimentally, with CO oxidation as the probe reaction. The intrinsic intimacies among them are (a) CuO-CeO2 > NiO-CeO2 and (b) CuO-γ-Al2O3 < NiO-γ-Al2O3; that is, the copper species is preferentially distributed on ceria, and the nickel species is mainly on the surface of alumina, when the copper and nickel species are coimpregnated onto the hybrid nanosupports. The intimate inhomogeneity at the nanoscale could be further applied to research and design of complex catalysts.
