Bridging the Gap between Industrial and Well‐Defined Supported Catalysts

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 years, there is often a very limited understanding about the structure of the catalytically active sites.

Description
Summary: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 years, there is often a very limited understanding about the structure of the catalytically active sites. This Review discusses how surface organometallic chemistry (SOMC) engineers surface sites with well‐defined structures and provides insight into the nature of the active sites of industrial catalysts; the Review focuses in particular on olefin production and conversion processes. Learning in concert: Some of the workhorse industrial catalysts used in a broad range of olefin production and conversion processes are based on ill‐defined metal sites isolated at the surface of oxide supports. The corresponding well‐defined surface species obtained by surface organometallic chemistry (SOMC) provide highly active catalysts and insight about the nature of the active sites in the industrial catalysts.
