Enhanced selectivity and stability of Pt-Ge/Al2O3 catalysts by Ca promotion in propane dehydrogenation

Sajjad Rimaz et al.

Summary: The addition of Ca reduced the acid centers of Al2O3 and increased the degree of alloy formation, leading to enhanced propylene selectivity and catalyst stability. The Ca-promoted catalyst showed lower deactivation rate and higher residual activity compared to the non-promoted catalyst, resulting in better performance in terms of activity and selectivity at steady state conditions.

Pt-Sn Supported on Beta Zeolite with Enhanced Activity and Stability for Propane Dehydrogenation

Su-Un Lee et al.

Summary: This study investigates the catalytic properties of Pt-Sn catalysts supported on Beta zeolites for propane dehydrogenation (PDH) reactions. Compared to other supports, Beta zeolite-supported Pt-Sn catalysts show better propylene selectivity and achieve optimal performance after a proper reaction time. The differences in catalytic behavior are attributed to the physicochemical properties and reaction mechanism of Beta zeolite-supported Pt-Sn catalysts.

Subsurface-Regulated PtGa Nanoparticles Confined in Silicalite-1 for Propane Dehydrogenation

Bofeng Zhang et al.

Summary: Propane dehydrogenation (PDH) is a promising technique to produce propylene, but Pt-based catalysts often suffer from stability issues. This study investigated the surface and subsurface composition of supported PtGa nanoparticles and demonstrated that subsurface regulation can enhance propylene selectivity. Furthermore, PtGa alloy nanoparticles encapsulated in MFI zeolite showed enhanced catalytic stability.

Tandem In2O3-Pt/Al2O3 catalyst for coupling of propane dehydrogenation to selective H2 combustion

Huan Yan et al.

Summary: The study demonstrated that growing In2O3 over Pt/Al2O3 using atomic layer deposition results in a nanostructure that kinetically couples domains through surface hydrogen atom transfer, improving the selective oxidative dehydrogenation of propane. In contrast, other nanostructures, such as Pt on In2O3 or Pt mixed with In2O3, were unable to organize the reactions effectively, resulting in more propane combustion.

Regulating coordination number in atomically dispersed Pt species on defect-rich graphene for n-butane dehydrogenation reaction

Xiaowen Chen et al.

Summary: By introducing atomically dispersed Sn promoters, fully exposed Pt-3 clusters were successfully fabricated on defective nanodiamond@graphene, showing higher conversion and remarkable alkene selectivity in n-butane direct dehydrogenation reaction compared to typical Pt NP and Pt SA catalysts. The study correlated dehydrogenation activity with the average coordination number of Pt-Pt bond, providing insights into the structure effects on the reaction at the atomic level.

On the Role of Sn Segregation of Pt-Sn Catalysts for Propane Dehydrogenation

Jieli Wang et al.

Summary: This study demonstrates that the recoverable Pt3Sn alloy surface structure through Sn segregation enables efficient propane dehydrogenation catalysis with high selectivity and stability, even after undergoing multiple cycles of acid etching-reduction procedures. The migration of Sn atoms from the core to the surface plays a crucial role in the recovery process, as confirmed by various characterization techniques and theoretical calculations.
