Promoters can significantly affect the activity and selectivity of a catalyst, even at their low concentrations in catalysts. In this work, we designed and synthesized CuO catalysts with atomically dispersed co-promoters of Sn and Zn. When used as the catalyst in the Rochow reaction for the synthesis of dimethyldichlorosilane, this catalyst ... The electrochemical properties of the KMO electrodes were systematically evaluated. Fig. 3 a shows the CV curves of KMO nanosheets at a scan rate of 5 mV s −1 with the potential window ranging from 0.4 to 2 V.
