PROBLEM TO BE SOLVED: To provide a method for making a carbon material such as a vertically oriented CNT, a carbon nanowall, or the like uniformly support a metal thereon.SOLUTION: The method for producing the metal supporting carbon using a supercritical fluid utilizes an apparatus having a first vessel and a second vessel which is connected with the first vessel via a valve so as to be capable of communicating therewith, and includes (a) a step to seal a metal compound and a supercritical fluid precursor gas in the first vessel and carbon and the supercritical fluid precursor gas in the second vessel respectively, (b) a step to make the supercritical fluid precursor gas undergo a transition to a supercritical state by pressurizing the first vessel and the second vessel respectively in such a way that pressure in the first vessel gets lower than that in the second vessel, and (c) a step to make the first vessel and the second vessel communicate with each other by opening the valve. |
