Synthesis gold and jade type core shell structure Pt@Sn in deboronated MWW zeolite and its good performance for light alkane dehydrogenation

Recent progress in the development of catalysts for propane dehydrogenation in the presence of CO2

“…A Pt@Sn core–shell structure generated in MWW zeolite was prepared by Liu et al 91 by planting incorporation of Sn and deposition–precipitation (DP) loading Pt. They found that at 650 °C and C 3 H 8 to CO 2 ratio of 0.5, the propane conversion of the Pt@Sn/MWW catalyst (61%) was twice that of the Pt/MWW catalyst prepared by the impregnation method (30%).…”

“…CO 2 is mainly involved in the coupling reaction through RWGS, and thus additional active sites are needed for CO 2 activation over Pt-based catalysts. The involvement of oxidative species (CO 2 and H 2 O) brings new challenges in the design of highly efficient catalysts, which is different from that of propane direct dehydrogenation 90–92 and will be discussed in the current review. Several reviews on the development of metal or metal oxides for propane dehydrogenation have been reported in recent years.…”

Copper-Promoted Platinum Supported on HSSZ-13 Zeolite Catalysts for Propane Dehydrogenation to Propylene

“…The most commonly used promoter for Pt-based catalysts is Sn. As a promoter, Sn has both geometric and electronic effects. − Zhang et al synthesized PtSn catalysts for propane dehydrogenation, which supported by dendritic mesoporous silica nanoparticles . The addition of Sn increased the dispersion of Pt, improved the electronic state of Pt, improved the conversion of propane, and reduced the catalyst’s rate of deactivation.…”
