| 摘要 |
An embodiment of the present invention comprises a ceramic catalyst comprising a porous ceramic/silica glass substrate having substantially interconnecting pores with an average pore size of approximately 2 micron or less and particles comprising one or more noble metals on the surface of the substantially interconnecting pores. The noble metal particles may be either amorphous and/or crystalline nano-particles. The noble metals preferably may comprise silver, gold, rhodium, and/or palladium. The average pore size may be approximately 1 micron or less, 0.5 microns or less, 0.3 microns or less, 0.2 microns or less, 100 nanometers or less, 50 nanometers or less, or between 50 nanometers and 150 nanometers. Other embodiments of the present invention are directed to methods of manufacturing the ceramic catalyst and novel glass compositions used to manufacture the ceramic catalyst and using the ceramic catalyst at temperatures above 200° C. to produce hydrogen gas and to store hydrogen gas.
