The chemical industry relies on catalytic processes, which involve mainly heterogeneous
catalysts because they offer many advantages over their homogeneous counterparts such …

Because of their extensive use as chemical building blocks, light olefins, such as propylene
(propene) and ethylene (ethene), are among the most important types of compounds in the …

Many industrial catalysts contain isolated metal sites on the surface of oxide supports.
Although such catalysts have been used in a broad range of processes for more than 40 …

Model systems are very important to identify the working principles of real catalysts, and to
develop concepts that can be used in the design of new catalytic materials. In this review we …

Abstract Hf‐, Sn‐, and Zr‐Beta zeolites catalyze the cross‐aldol condensation of aromatic
aldehydes with acetone under mild reaction conditions with near quantitative yields. NMR …

We report the synthesis, characterization, and catalytic performance for gas phase propane
dehydrogenation of single-site Co 2+ ions supported on silica. Spectroscopic …

We report a comparative study of isolated FeII, iron oxide particles, and metallic
nanoparticles on silica for non-oxidative propane dehydrogenation. It was found that the …

Single-site gallium centers on the surface of silica are prepared via grafting of [Ga (OSi
(OtBu) 3) 3 (THF)] on SiO2–700 followed by a thermolysis step. The resulting surface …

Conspectus Heterogeneous catalysts are complex by nature, making particularly difficult to
assess the structure of their active sites. Such complexity is inherited in part from their mode …

Higher olefins produced via ethylene oligomerization are versatile commodity chemicals
serving a vast range of industries with large global economic impact. Nickel aluminosilicates …
