The surface area of a zinc oxide composition is increased, and stabilized to heating, by incorporation of a tri or tetravalent metal, especially aluminium or gallium, e.g. in the form of a spinel with the zinc oxide. The composition is preferably made by coprecipitation of zinc and a compound of said metal and then calcination. The zinc oxide composition may also incorporate a Group VIII metal and be used as a catalyst for a Fischer Tropsch process. |
