Research on the Stability of Pd-Based Multi-Component Supported Catalysts

Abstract:

Based on SEM, FT-IR and XRD characterization, the catalyst Pd-Fe-Co-Ce/FSC (ratio 1:1:1:3) was calcined at a temperature of 550°C and a calcination time of 3 h. The catalyst is applied to the catalytic wet oxidation treatment of difficult-to-biodegradable organic waste-water. By the characterization of the catalyst before and after the reuse, it is verified that the SEM morphologis of the catalyst changed little, and the groups contained in the catalyst characterized by FT-IR hardly changed, and the XRD characteristic peaks did not change. From the SEM photos of the catalyst before and after use, the morphology of the catalyst does not change much, and the agglomerated support on the catalyst surface is slightly reduced; the absorption peaks of the FI-IR spectrum of the catalyst before and after use are not significantly different, indicating that the functional groups contained in the catalyst have not changed significantly; After using the catalyst, compared with before use, the characteristic peak shape of each characteristic diffraction did not change significantly. The results show that the catalyst Pd-Fe-Co-Ce/FSC (ratio 1:1:1:3) revealed a stable catalyst performance in the process of CWAO for the treatment of difficult-to-biodegradable organic waste-water.
