Structure Sensitivity in the Subnanometer Regime on Pt and Pd Supported Catalysts
… nanoparticles for various reactions including hydrogenation reactions. However, the relationship between metal nuclearity, electronic and their unique catalytic properties are still unclear. Thus, it is crucial to establish their relations for better future catalyst design. Ethylene …

Fundamental Understanding of Palladium-Based Catalysts: From Pyrene-Based COFs to Size-Controlled Bimetallic Nanostructures
… range of industrial chemical processes. Ethylene hydrogenation has long been used as a model reaction in heterogeneous catalysis to better understand the mechanism of selective acetylene hydrogenation over metal catalysts. Improving selectivity often depends on how strongly the reactants adsorb …

Structure Sensitivity of Alkanes Hydrogenolysis and Alkynes Hydrogenation on Supported Ir Catalysts
… but reduced at different temperatures. Acetylene hydrogenation is structure sensitive on Ir/ZnAl2O4 catalysts and the activity and selectivity are mainly determined by Ir nuclearity instead of the difference in electronic properties. The Ir single atoms and subnanometer clusters are more …

Novel routes for synthesis of Pd nanoparticles and faceted ZnO supports for heterogeneous catalysts
Alcohol steam reforming is a promising source of hydrogen as fuel, and could be improved by the use of an optimal catalyst. The methanol steam reforming reaction, CH3OH+H2O --> 3H2+CO2 frequently conducted by means of a Cu/ZnO catalyst. Unfortunately, this catalyst deactivates quickly and is …

Experimental and modeling studies using packed bed reactors: Liquid phase ethylene production by hydrogenation of acetylene
<p>"Gas-phase catalytic hydrogenation of acetylene to produce ethylene, commonly practiced in industries, has green oil formation, which leads to catalyst deactivation and sometimes reactor runaway risks due to high exothermicity. To overcome these issues as well as to increase the selectivity and …
