Developing an efficiently supported Cu-based catalyst with promoters to substitute the existing non-supported Cu-based catalysts is highly desirable to the Rochow-Müller reaction. Using a simple ball-milling method and CeO_(2) support, we prepared a high-performance CuO-ZnO-P-Sn/CeO_(2) catalyst by integrating highly dispersed multicomponent promoters of ZnO, Sn, and P with the active component CuO. This catalyst shows a significantly enhanced dimethyldichlorosilane selectivity because these promoters can substantially increase the Cu+ content and the formation of an active CuxSi phase. This work provides a new approach to efficiently designing Cu-based catalysts for the Rochow-Müller reaction.

Noble metals(NMs) supported on metal oxides are widely used in many important catalytic processes, such as catalytic oxidation reactions and hydrogenation reactions. It has been shown that the metal oxides s upports not only help to disperse NM nanoparticles(NPs) well but also significantly affect catalytic performance through their interactions with supported NM nanoparticles. Metal oxides nanoislands supported on metal surfaces have received increasing attentions in the past two decades. This work reports a comparative study of soot oxidation over synergistic Pt-Ce catalysts prepared by sequential deposition of the metals. The XRD patterns(Fig. 1) of Pt-Ce catalysts possess the diffraction peaks of alumina, platinum and ceria. The addition of CeO can limit the growth of Pt nanoparticles. It can be seen in Fig. 2 that the O desorption peak(β) of CeO/Pt/AlO appear in stronger intensity and at lower temperature compared to other catalysts. The metal deposition order in Pt–Ce catalyst can influence their activity due to different Pt-Ce interfaces. As shown in Table 1, the activity of the catalysts for soot oxidation under loose contact conditions increases in the sequence of CeO/Pt/AlO > Pt/CeO/AlO > CeO/AlO > CeO/AlO.
