| 英文摘要 | nitrogen-containing ordered mesoporous carbons (nomcs) characteristic of cmk-3 were nanocasted from mesoporous silica sba-15 using aniline as carbon precursor. the influence of synthesis condition on the structural parameters of nomcs were systematically investigated using n-2 adsorption, powder x-ray diffraction (xrd), transmission electron microscopy, x-ray photoelectron spectroscopy (xps), elemental analysis and thermogravimetric analysis (tga). the 2d hexagonally ordered nitrogen-containing mesoporous carbon could be synthesized in a wide temperature range (600-950 degrees c), with brunauer-emmett-teller (bet) surface area varying from 988 to 1166 m(2)/g and pore size tunable from 2.7 to 3.3 nm. the n/c molar ratio in the framework of mesoporous carbon was found to be highly dependent on the synthesis condition and reduced from 9.5% to 4.8% as the synthesis temperature increased from 600 to 950 degrees c. xps showed that nitrogen atoms were incorporated in graphitic sheets as quaternary nitrogen and pyridine-like nitrogen. the ca. 0.6 ev lower binding energy of pt nanoparticles in contrast to that of bulk pt indicated a strong interaction between nitrogen atoms and pt nanoparticles, which was critical to the uniform dispersion of pt nanoparticles on the nitrogen-containing mesoporous carbon. the co stripping peak potentials depended on both the n/c ratio as well as pt particles size. the activities of methanol oxidation on pt/nomcs were investigated by cyclic voltammograms and electrochemical impedance spectroscopy (eis). the pt/nomcs showed generally high co tolerance and comparable activity to pt/xc-72 under the identical condition.
