| 中文摘要: |
| 以Co（NO3）2·6H2O和1-丁基-3-甲基咪唑氢溴酸盐为前驱体，Vulcan XC72R为载体，采用浸渍法制备负载型Co-N-C催化剂，使用XRD、XPS、HRTEM等手段对其结构进行了表征.以α-芳香醇催化氨氧化合成α-芳香腈为考察对象，对其催化性能进行了评价.例如，在O2压力为0.5 MPa，反应温度为120℃，反应时间为20 h的条件下，以Co-N-C/700为催化剂，NH3（aq）为氨源，在催化苯甲醇合成苯甲腈反应中，苯甲醇转化率可达100%，产物苯甲腈选择性为100%. |
| 英文摘要: |
| Using Co(NO3)2·6H2O and 1-butyl-3-methylimidazole hydrobromide as precursors, and Vulcan XC72R as the supporter, the supported Co-N-C system was prepared by the impregnation method. Its structure was characterized by X-ray diffraction (XRD), X-ray electron spectroscopy (XPS), and High Resolution Transmission Electron Microscope (HRTEM), etc. The catalytic performance was evaluated by studying the process of its catalytic ammoxidation of α-aromatic alcohol to α-aromatic nitrile. For example, under the conditions of 120 ℃, O2 pressure 0.5 MPa, and reaction time for 20 h, with Co-N-C/700 as the catalyst, NH3(aq) as the ammonia source, in the catalytic reaction of benzyl alcohol to benzonitrile, the conversion of benzyl alcohol can reach 100%, and the selective of the productbenzonitrileis 100%. |
