The reduction of nitrobenzene catalyzed by different carbon materials (mainly carbon nanotubes) was studied. TGA, TPD, TEM, N_2 adsorption-desorption, and Raman spectroscopy were used to show that it was oxygenated groups that gave catalytic activity, while the surface area, pore struc-ture, morphology, structural defects and Fe impurities in the catalysts did not have a significant influence on the activity. The carbonyl group played an important role, but the carboxylic group and anhydride adversely affected the reaction. The conjugated π system, which was necessary for elec-tron transfer and nitrobenzene adsorption, was another critical factor. The reaction proceeded through the direct route in which the intermediate nitrosobenzene was converted directly to aniline quickly. |

本文对碳材料(主要是碳纳米管)催化硝基苯的还原反应进行了系统研究。通过热重分析、程序升温脱附、透射电子显微镜、物理吸附以及拉曼光谱等表征,发现碳材料表面的含氧官能团在反应中起着重要的作用,而比表面、孔结构、形貌、结构缺陷以及可能存在的铁杂质对反应没有显著影响。羰基的作用非常重要,但是羧基和酸酐对反应不利。除此之外,材料的π电子体系也很关键,因为它可以传递电子,并且利于硝基苯的吸附。硝基苯还原按照直接路径进行,反应过程中生成的中间体亚硝基苯可以迅速转化为苯胺。 |
