Cooperative Catalysis of Vibrationally Excited CO and Alloy Catalyst Breaks the Thermodynamic Equilibrium Limitation.

Using nonthermal plasma (NTP) to promote CO hydrogenation is one of the most promising approaches that overcome the limitations of conventional thermal catalysis. However, the catalytic surface reaction dynamics of NTP-activated species are still under debate. The NTP-activated CO hydrogenation was investigated in PdGa/SiO alloy catalysts and compared to thermal conditions.

Synthesis of CoFeGe Heusler alloy nanoparticles and catalysis for selective hydrogenation of propyne.

Although intermetallic compounds are attracting attention of catalysis researchers, ternary intermetallic catalysts have scarcely been investigated due the difficulty of synthesizing supported nanoparticles. In this study, we successfully synthesized SiO supported CoFeGe Heuslar alloy nanoparticles. This catalyst exhibited high catalytic performance for selective hydrogenation of propyne by nano-sizing.

Electroassisted Propane Dehydrogenation at Low Temperatures: Far beyond the Equilibrium Limitation.

Propylene production by propane dehydrogenation (PDH) generally requires high temperatures due to thermodynamic equilibrium limitations. This study developed a novel type of catalytic system for low-temperature PDH by combining a surface protonics methodology with intermetallic active sites. By application of an electric current, the intermetallic Pt-In/TiO catalyst gave a propylene yield of 10.

Doubly Decorated Platinum-Gallium Intermetallics as Stable Catalysts for Propane Dehydrogenation.

Propane dehydrogenation (PDH) is a promising chemical process that can satisfy the increasing global demand for propylene. However, the Pt-based catalysts that have been reported thus far are typically deactivated at ≥600 °C by side reactions and coke formation. Thus, such catalysts possess an insufficient life.
