Microwave Synthesis of Bimetallic Nanoalloys and CO Oxidation on Ceria-Supported Nanoalloys
Abstract
A facile and fast microwave irradiation (MWI) method has been developed to prepare a wide variety of pure metallic and bimetallic alloy nanoparticles with controlled size and shape. The important advantage of microwave dielectric heating over convective heating is that the reactants can be added at room temperature (or slightly higher temperatures) without the need for high-temperature injection. The method allows the passivation of the nanocrystals by using a mixture of olyel amine and oleic acid as a solvent, a reducing agent, and a capping material. We investigate the controlled synthesis of nanoalloys among the nanocrystals of Au, Ag, Pt, Pd, Ru, Rh, Cu, and Ni by studying the changes in the structural and optical properties of the resulting nanoalloys with respect to the individual metals. Using the same method, we also report the synthesis of selected nanoalloys supported on ceria nanoparticles as nanocatalysts for CO oxidation. The catalytic activities for CO oxidation are presented and discussed. High activity and thermal stability have been observed for the nanoalloys according to the order CuPd > CuRh > AuPd > AuRh > PtRh > PdRh > AuPt. The method could be applied for the synthesis of multimetallic nanoalloys with novel properties resulting from the different metallic properties coupled together in a single nanoalloy.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
