Recent progress in catalytic dehydrogenation of propane over Pt-based catalysts.

Light alkenes are the key building blocks in the chemical industry. As a propene on-purpose production technology, propane dehydrogenation has drawn particular attention due to the growing demand for propene and the discovery of large reserves of shale gas. The development of highly active and stable propane dehydrogenation catalysts is significant in the world-wide research field.

Dendritic Mesoporous Silica Nanoparticle Supported PtSn Catalysts for Propane Dehydrogenation.

PtSn catalysts were synthesized by incipient-wetness impregnation using a dendritic mesoporous silica nanoparticle support. The catalysts were characterized by XRD, N adsorption-desorption, TEM, XPS and Raman, and their catalytic performance for propane dehydrogenation was tested. The influences of Pt/Sn ratios were investigated.
