Preparation of Palladium-Impregnated Ceria by Metal Complex Decomposition for Methane Steam Reforming Catalysis

Figure 1

XRD patterns of the obtained products of (a) ceria after the thermal decomposition of the metal complex at 600°C for 2 h, further used as a catalytic support; (b) ceria support after microwave-assisted wetness impregnation of palladium(II) nitrate (3% mole); (c) Pd-impregnated ceria catalyst after calcination under reduced atmosphere of 10% H₂ in He stream at 700°C for 2 h, denoted as 3Pd-CeO2-T-N (red curves) and 3Pd-CeO2-B-N (blue curves) with regard to the use of cerium(III) nitrate to prepare metal complexes with triethanolamine and benzoxazine dimer ligand, respectively.
