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. 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.

Eine Brücke zwischen industriellen und wohldefinierten Trägerkatalysatoren

et al. 2018

View full text Add to dashboard Cite

Viele industrielle Katalysatoren enthalten isolierte Metallzentren an der Oberfläche von Oxidträgern. Derartige Katalysatoren werden seit über 40 Jahren bei verschiedensten Verfahren verwendet – die Struktur ihrer katalytischen Zentren bleibt aber bis heute nur ungenügend verstanden. Dieser Aufsatz zeigt, wie mit metallorganischer Oberflächenchemie (SOMC) Oberflächenzentren mit gut definierten Strukturen erzeugt werden können, und beschreibt die Beschaffenheit aktiver Zentren in industriellen Katalysatoren, insbesondere für die Herstellung und Umwandlung von Olefinen.

“…Li [30] combined NiSO4 with rhenium oxide to gamma-Al2O3 by 59% in ethene and 49% in propene selectivity. Lavrenov [1,31] followed a similar approach, but with PdO and Re2O7 on ZrO2. At a temperature of 80°C, 86% conversion and 65.4% propene could be obtained.…”
