Abstract

A catalyst material for purification of gases and liquids and a process for preparing it. The catalyst material includes a catalytically inert support body with at least one metal oxide coating deposited on the support body. The support body consists of a ceramic material with a macropore system as well as a micro- and/or a mesopore system. The ceramic material is produced by mixing clay, preferably kaolin, with at least one combustible material, which mixture by means of pelletizing, extruding or the like is formed to bodies, which are burnt at a temperature preferably within the range of 1000-1200 DEG C. One or more metal oxides are deposited on the support bodies by impregnating them with an aqueous solution of at least one metal salt, whereupon the metal salt by contact with one or more alkaline substances is precipitated as a metal hydroxide. The support bodies are subsequently dried and heated to a temperature of 200-900 DEG C, whereby the precipitated metal hydroxyde is calcined to the corresponding oxide.
