  journal={Reaction Kinetics, Mechanisms and Catalysis},
Carbon-doped alumina (CDA) beads with different carbon contents were prepared by an ammonium alginate (ALG) assisted sol–gel method via changing the concentration of ALG in preparation process, which were used as the support of Pt–Sn–K catalysts. XRF, XRD, BET, TEM, EDS, NH 3 -TPD, TG and Raman techniques were employed to characterize the physical–chemical properties of CDA materials and Pt–Sn–K catalysts. Results showed that the as-prepared CDA materials all contained carbon and the carbon… Expand
