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… 

MgF2-Modified Hydrotalcite-Derived Composites Supported Pt-In Catalysts for Isobutane Direct Dehydrogenation

Here, a simple method was developed to prepare an MgF2-modified hydrotalcite-derived composite, which was used as support for the Pt-In catalyst for isobutane direct dehydrogenation. The catalysts,

TLDR
The as-prepared CCA possessed the texture of alumina and the surface properties of carbon or both carbon and alumina depending on the carbon coverage and number of carbon layers in CCA.

Influence of support on the catalytic properties of Pt–Sn–K/θ-Al2O3 for propane dehydrogenation

A study on the performance of Pt(0.3 wt%) Sn(0.2 wt%) K(0.5 wt%) catalysts supported on four different theta-Al2O3 for propane dehydrogenation is reported in this study. The theta-Al2O3 used as
