<P>PROBLEM TO BE SOLVED: To provide a mechanocatalyst for decomposing water using one of or a mixture of a metal, a semiconductor, a compound and an alloy and mainly producing only hydrogen with the remarkable decrease of the production of oxygen and an apparatus and a method of decomposing water with the catalyst. <P>SOLUTION: In the apparatus 1 for decomposing water by a mechanocatalysis provided with a reaction vessel 4 housing a suspension 3 containing the mechanocatalyst 2 and water or a solution containing water, a stirrer 5 arranged in the reaction vessel 4 and a stirring apparatus 6 for rotating the stirrer 5, the mechanocatalyst 2 is a fine particle of one of the metal, the semiconductor, the compound and the alloy and for mainly producing hydrogen by the decomposition of water. The apparatus can be provided with an inert gas supply part 8 for degassing the suspension 3. The quantity of hydrogen to be produced is increased when using particularly Ti, Si, Al, Ti-Nb, Ti-Fe, TiSi<SB>2</SB>, Raney iron, ArSi<SB>2</SB>, a Devard's alloy or the like as the mechanocatalyst. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
