Nanocomposite copper-ceria catalysts are provided, which comprise copper oxide nanoparticles, copper nanoparticles, or a mixture thereof combined with ceria nanoparticles. Methods for making such catalysts are also provided, which involve the steps of (i
A series of Cs promoted copper oxide catalysts were prepared by co-precipitation method and tested for the direct decomposition of nitrous oxide (N2O). The Cs promoted catalysts were more active particularly with a molar ratio of Cs/Cu at 0.1 compared to bulk CuO. Methods of XRD, BET, XPS...
PURPOSE:To enable to decompose the cyanide with very small quantity of hypochlorite, by removing the precipitate, educed during the decomposition process, at the time of decomposing free CN<-> or metallic cyan complex ion etc., coexisted with metal, under the existence of hypochlorite, alkali an...
The synthesis of the novel copper(I) precursor [Cu(PPh3)2(O2CCH2OC2H4OC2H4OCH3)] and its application in the straightforward solution synthesis of oxide-free copper nanoparticles by mere thermal decomposition are reported; depending on the precursor concentration particles of sizes of 10 nm or 30 ...
