A catalyst for use in an oxidation reaction comprises a porous alumina support in the form of pellets or powder, preferably powder. The porous alumina support has captured thereon a complex comprising gold, a transition metal selected from cobalt or manganese, and 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 1:10 to 1:200. |
