<P>PROBLEM TO BE SOLVED: To decompose ammonia, especially ammonia contained in gas over a wide range of from low to high concentrations. <P>SOLUTION: This ammonia decomposing catalyst is obtained by supporting at least one kind of the elements (platinum group elements) selected from the group consisting of VIII-X elements to a metal oxide of which acid strength (H<SB>0</SB>constant) is -5.6 or above (low acid strength oxides). Preferably, the low acid strength oxides are aluminum oxide, cerium oxide, magnesium oxide and titanium oxide. <P>COPYRIGHT: (C)2010,JPO&INPIT |
