Supported cold-complex oxidation catalyst

摘要

A catalyst for use in an oxidation reaction comprises a porous alumina support having captured thereon a complex comprising gold, a transition metal selected from cobalt and manganese, and the alumina, the concentration of gold on the support being less than 2 percent by mass of the catalyst, and the atomic ratio of gold to transition metal being in the range 1:30 to 1:200. The oxidation reaction may be the oxidation of carbon monoxide or a hydrocarbon.
