| 英文摘要 | A novel procedure is reported for synthesizing well-dispersed Pt catalyst supported on nitrogen-containing mesoporous carbon nanocomposite (CMN(subscript x)) based on pyrolysis of carbon and Pt precursors in a N-trimethoxysilylpropyl-N, N, N-trimethylammonium chloride (TPTAC) functionalized mesoporous silica, suchas SBA-15, by co-condensation. The Pt-CMN(subscript x) so fabricated possesses not only Pt-N active sites but also high surface areas and extended pores (ca. 4 nm) requisite for oxygen mass transfer. Accordingly, superior electrocatalytic performance was observed for Pt-CMN(subscript x), rendering practical applications in hydrogen-energy related areas, for examples, as supported cathodic electrodecatalysts for PEMFCs and DMFCs. |
