【摘要】 以不同有机物(邻苯二酚、间苯二酚、对苯二酚、乙二醇、环己胺)为辅助炭源,通过直接炭化含柠檬酸及磷酸铝的复合物制备了一系列纳米孔炭材料(NC),采用多种表征手段研究了辅助炭源对最终炭材料性质的影响.结果表明,NC材料的结构和表面官能团性质随辅助炭源的变化而改变,其中以间苯二酚、对苯二酚、环己胺为辅助炭源制备的炭材料在空气氧化苯甲醇反应中表现有较高的催化活性.更多还原

【Abstract】 Different organic compounds, o-dihydroxybenzene, m-dihydroxybenzene, p-dihydroxybenzene, glycol, and cyclohexylamine, were used as the extra carbon source for a series of nanoporous carbon (NC) materials prepared by directly carbonizing composites containing citric acid and aluminum phosphate. The effect of the extra carbon source was studied. The structure and surface functional groups on the NC material were different with different extra carbon sources. The NC materials prepared using m-dihydroxybenzene, p-dihydroxybenzene or cyclohexylamine have excellent catalytic activity for the aerobic oxidation of benzyl alcohol to benzaldehyde.更多还原
