To provide a method capable of producing a molded body of aluminum oxide and titanium oxide mixture having a fine-pore volume larger than that heretofore without damaging mechanical strength.
This method comprises mixing aluminum oxide powders and titanium oxide powders in which a ratio (I002/I200) of the peak intensity (I002) of the 002 plane to that (I200) of the 200 plane is ≤2, with a fine pore-imparting agent of ≥5 pts.mass based on 100 pts.mass of the sum of aluminum oxide and titanium oxide powders, molding the above mixture and then firing. The powder of a resin selected from methacrylic resin, olefinic resin and crystalline cellulose is exemplified as the fine pore-imparting agent. Thereby, it is possible to obtain the molded body having pressure-proof strength of ≥0.40 daN/mm2 and a fine pore volume of ≥0.2 cm3/g. A catalyst for oxidizing hydrogen chloride obtained by supporting ruthenium oxide on the molded body is used for production of chlorine by reaction of hydrogen chloride with oxygen.
