Investigation of the effect of bimetallic Zn-Mg modified Al2O3 carriers modulating Ag species on the performance of H2-assisted C3H6-SCR and the mechanism

Significant Enhanced SO2 Resistance of Pt/SiO2 Catalysts by Building the Ultrathin Metal Oxide Shell for Benzene Catalytic Combustion

“…The Mg 1s XPS spectrum is shown in Figure 10a with a peak at around 1305.1 eV, which was identified as the Mg 2+ state. 49,50 It could be seen that after the reaction of the Pt/ SiO 2 @MgO catalyst in the SO 2 atmosphere, the relative content of Mg elements on its surface decreased, which was consistent with the data change in Table 5. In addition, the binding energies of the Zn 2p spectra were 1046.0 and 1022.9 eV, respectively (Figure 10b), indicating the presence of Zn 2+ species.…”
