  • Title: [Characterization of the Pt/CeO2-ZrO2/Al2O3 catalysts by spectra].
    Author: Zhan Y, Zheng Q, Wei K, Xiao Y, Cai G, Chen T, Zhang H.
    Journal: Guang Pu Xue Yu Guang Pu Fen Xi; 2000 Oct; 20(5):709-11. PubMed ID: 12945428.
    Abstract:
    The performance of Pt/Al2O3 catalysts with CeO2-ZrO2 in difference ways was studied by NIR-FT-Raman, BET, H2 chemisorption, XRD. It shows that the dispersion of Pt on Al2O3 is improved with the increasing of dispersion of CeO2-ZrO2 on the surface of Al2O3, owing to the strong interacting between CeO2-ZrO2 and Pt. And adding with salts is priority.
