<P>PROBLEM TO BE SOLVED: To provide a base material for supporting a catalyst comprising a composite oxide having an extremely higher specific surface area than before, its manufacturing method and the catalyst using the base material. <P>SOLUTION: The base material for supporting the catalyst comprises the composite oxide, which includes at least two kinds of metal elements, having a specific surface area of 250 m<SP>2</SP>/g or above and having the peak of a pore distribution at 1-10 nm. This base material comprising the composite oxide is obtained by impregnating a carbon nanotube with a liquid containing a precursor of the composite oxide to support the composite oxide on the carbon nanotube and subsequently allowing the carbon nanotube to disappear. The catalyst is constituted by supporting a catalytic component on the base material. The manufacturing method of the base material for supporting the catalyst using the carbon nanotube and the precursor of the composite oxide is also disclosed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
