Bimetallic Ni-Zn site anchored in siliceous zeolite framework for synergistically boosting propane dehydrogenation

Chengming Huang et al.

Summary: Propane dehydrogenation (PDH) is a promising benign process for the production of propylene, but traditional catalysts suffer from rapid deactivation. The study successfully designed a novel bimetallic-site catalyst NiZn-S-1 with high catalytic activity and stability, providing a potential alternative for PDH catalysts in the future.

The active sites and catalytic properties of CrOx/Zn-Al2O3 catalysts for propane dehydrogenation

Huaiqi Shao et al.

Summary: The CrOx/Zn-Al2O3 catalysts supported on Zn-modified alumina showed uniform foamed pores, high specific surface area, and large pore size. The zinc modification improved the dispersion of Cr6+ species and promoted the formation of active chromate species on the surface, enhancing propane conversion and propylene yield. Additionally, the zinc modifier inhibited the formation of coke deposition, leading to increased catalyst stability.

Promoting propane dehydrogenation via strain engineering on iridium single-atom catalyst

Weiyu Song et al.

Summary: This study systematically investigates the effect of strain on propane dehydrogenation over the nitrogen-coordinated iridium single-atom catalyst (IrN4). It is found that compressive strain can promote the first dehydrogenation while tension strain hinders it, providing guidance for improving the performance of PDH. The selectivity of PDH over IrN4 SAC to propylene is not qualitatively affected by the applied strain, which is significant for practical applications.

Dehydrogenation of propane in the presence of CO2 on GaOx/SiO2 catalyst: Influence of the texture characteristics of the support

Marina A. Tedeeva et al.

Summary: This study investigates the effect of support nature on the catalytic activity of GaOx/SiO2 catalytic systems. The results indicate that a high dispersion of Ga2O3 particles on the support surface and a low acidity of the catalyst can achieve high catalytic activity. The catalyst supported on SiO2 with a larger surface area and a gallium content of 7 wt% exhibits the best performance.

Oxidative Dehydrogenation of Propane into Propene over Chromium Oxides

Cedric Karel Fonzeu Monguen et al.

Summary: A series of chromium oxide catalysts (CrOx) were prepared using the sol-gel method for oxidative dehydrogenation of propane into propene (ODHP). The catalysts were characterized after calcination, and Cr-300 showed the best catalytic activity and stability due to its small crystallite size, large specific surface area, and unique material structure.

Oxidative Dehydrogenation of Propane with Carbon Dioxide Catalyzed by ZnxZr1-xO2-x Solid Solutions

Guo-Qing Yang et al.

Summary: In this study, ZnO-ZrO2 composites were investigated as catalysts for the oxidative dehydrogenation of propane with CO2. It was found that a pure ZnxZr1-xO2-x solid solution was formed over ZnO-ZrO2 composites, and the amount of oxygen defects was directly proportional to the fraction of the solid solution. The catalytic performance was determined by the amount and mobility of lattice oxygen over the ZnxZr1-xO2-x solid solutions, with the best catalyst operating stoichiometrically via a redox mechanism.

Summary: Highly active Ga2O3 nanoparticles catalysts were prepared by one-step oxidative decomposition of gallium nitrate with sucrose-derived carbon foams (SCF) template. The addition of sucrose facilitated the higher surface area of Ga2O3 nanoparticles and morphological transformation from bulk to flake. The optimum catalytic activity was achieved over SXCF-Ga2O3 catalysts at the sucrose/Ga2O3 molar ratio of 6 with significant propane conversion and propene selectivity.
