| Abstract | In this paper, the regulating role of CoOx on deleterious Cl- over PdO/SiO2 for CO oxidation has been thoroughly studied. By comparing the catalyst prepared from Pd(NO3)2 and PdCl2, the deleterious effect of Cl- has been confirmed. The addition of CoOx leads to the significant temperature-dependent variation of catalysts performance. Calcination below 500 °C weakens the interaction between PdCl4 2- and silica and results in the remarkable agglomeration of Pd on the silica surface and low activity. However, the presence of CoOx is able to inhibit the agglomeration of PdO at high temperature, and leads catalyst showing higher activity. HRTEM and TPR results support this conclusion and indicate a stronger interaction between PdO and CoO in catalyst after the sample calcined at temperature higher than 500 °C, partially because of the complete decomposition of PdCl2 species. The addition of CoOx can stabilize PdO species, which provide more active centers for the adsorption of reactants. Results also indicated that the CO reaction oxidation occurs at the interface between PdO and CoOx. |
