20120088650 | MANUFACTURING METHOD FOR CATALYST CARRIER - After placing inside a reactor second container a substrate to which a CNT not yet carrying a catalyst is adhered under a sealed environment of supercritical carbon dioxide through which a Pt catalyst complex is dispersed, a temperature of the supercritical carbon dioxide is maintained below a decomposition temperature of the Pt catalyst complex, and a temperature of the CNT not yet carrying a catalyst is maintained at or above the decomposition temperature of the Pt catalyst complex by heating the substrate. Further, a pressure of the supercritical carbon dioxide is maintained at 7.5 MPa, which is slightly higher than a supercritical pressure (7.38 MPa) of carbon dioxide. The supercritical carbon dioxide is then caused to contact the CNT adhered to the substrate, and as a result, a Pt catalyst is carried on the CNT. | 04-12-2012 |
