Descrição geral

Copper powder (dendritic) is also known as an electrolytic copper powder (ECP) which has a dendritic shape with a particle size that is less than 4.5 μm. The dendritic shape of the copper particles can be produced by electrolytic deposition method.

Aplicação

ECP can be used as a catalyst in the production of biodiesel by transesterification of soybean oil and partial hydrogenation of polyunsaturated compounds. It can also be used to form a metal composite with carbon nanotubes for the formation of high strength copper alloys.

A method has been developed for the preparation of N-alkynylated sulfoximines involving the copper-catalyzed decarboxylative coupling of sulfoximines with aryl propiolic acids. A range of substituents on both the sulfoximidoyl moiety and the aryl group of the propiolic acid were...

Carbon monoxide (CO) produced in many large-scale industrial oxidation processes is difficult to separate from nitrogen (N2), and afterward, CO is further oxidized to carbon dioxide. Here, we report a soft nanoporous crystalline material that selectively adsorbs CO with adaptable...
