The work would be helpful to the development of novel Cu-based catalysts for organosilane synthesis. Copper is a highly reactive metal and it oxidizes (i.e., tarnishes) very easily, which means that even light use can leave a copper pot looking lackluster.

The enhanced catalytic performance may stem from the larger interfacial contact among the gas MeCl, solid Si particles, and solid Cu-based catalyst flakes, as well as the synergistic effect among the different Cu species.

Compared to the metallic Cu powder and Cu flakes, the controllably oxidized Cu flakes containing Cu, Cu 2O, and CuO species show much higher M2 selectivity and silicon conversion in the Rochow reaction. Copper oxidizes slowly in air, corroding to produce a brown or green patina. The samples were characterized by X-ray diffraction, temperature-programmed reduction, thermogravimetric analysis, oxidimetry analysis, particle size analysis, transmission electron microscopy, and scanning electron microscopy. These catalysts are explored in the Rochow reaction using silicon powder and methyl chloride (MeCl) as reactants to produce dimethyldichlorosilane (M2), which is the most important organosilane monomer in the industry. The metallic Cu flakes prepared by milling metallic Cu powder were controllably oxidized in air at different temperatures to obtain the Cu-based catalysts containing multicomponents of Cu, Cu 2O, and CuO.
