Abstract: PURPOSE: A catalytic decomposition process of hydrogen iodide and a catalyst manufacturing method thereof are provide to decompose the hydrogen iodide by using a catalyst which is stable in a reaction condition of high temperature. CONSTITUTION: In an iodine - sulfur hydrogen manufacturing process, a catalyst decomposing hydrogen iodide is a silica catalyst containing platinum group metals. A manufacturing method of the silica catalyst includes the following steps: manufacturing silica sol by agitating an ammonia solution and heating TEOS/EtOH liquid(S1); mixing mphiphilic triblock copolymer(EO20PO70EO20, Mav=5,800, Aldrich) dissolved in a hydrochloric acid solution(S3); forming gel by mixing tetraammineplatinum(II) hydroxide(S4); and reducing the catalyst to hydrogen gas(S5).
