https://en.wikipedia.org/wiki/Catalyst_support
In chemistry, a catalyst support is the material, usually a solid with a high surface area, to which a catalyst is affixed. The activity of heterogeneous catalysts and nanomaterial-based catalysts occurs at the surface atoms. Consequently, great effort is made to maximize the surface area of a catalyst by distributing it over the support.

Aug 24, 2005 · The present review discusses the most important aspects to take into consideration to improve the properties of γ‐Al 2 O 3 as a support for catalytic applications. We show that the synthetic route to γ‐Al 2 O 3 is the starting point that determines the micro‐ and macrostructure of the oxide and, consequently, allows control of the support characteristics.Cited by: 596

alumina. On the other hand, alumina is a typical support for catalysts. Many kinds of metal supported catalysts are prepared using alumina as their support. These two roles of alumina, i.e., as adsorbent and support, are clos ely related to each other due to two reasons. Firstly, most supported catalysts are prepared by impregnation.Author: Akane Miyazaki, Ioan Balint

Aug 01, 2018 · However, gamma-alumina is the most widely used as a support material for the HDS process catalysts because of its mechanical strength which makes the catalyst stable under the harsh reaction conditions of the HDS process. Also, the alumina structure includes acidic sites and has a high surface area and good porosity.Cited by: 28

The alumina in the kaolin was successfully leached and a cubic structure γ-alumina of high thermal stability was synthesized. The γ-alumina was then characterised and utilised as support for the bimetallic catalyst (Fe-Ni) using wet impregnation method. The produced catalyst was used to produce CNTs in a CVD reactor. The thermal
