| 摘 要： | 通过一种简易的方法在介孔碳CMK-3的孔道内负载氧化铜粒子制备Cu/CMK-3复合物,利用粉末X射线衍射、氮气吸附-脱附、透射电镜等手段对其进行表征.结果表明,氧化铜均匀地分散在CMK-3孔道中,CMK-3在负载氧化铜后仍有较大的比表面积.考察了载铜CMK-3对水中苯酚的吸附和低温干法催化氧化苯酚性能.吸附和循环使用结果表明,Cu/CMK-3对水中苯酚具有较大的吸附量和良好的催化氧化效率.热重-质谱(TG-MS)联用测试结果表明,吸附的苯酚在180℃左右开始被催化氧化为CO2和水,此时不会造成苯酚的脱附和介孔碳CMK-3的烧蚀.

| Abstract: | Copper (II) oxide nanoparticles were incorporated into the pore system of mesoporous carbon CMK-3 by a facile method,forming the composite Cu/CMK-3. Cu/CMK-3 was characterized by powder X-ray diffraction,nitrogen physisorption,and transmission electron microscopy. Results showed that Cu/CMK-3 preserved the ordered mesoporous structure of CMK-3 and copper (II) oxide was dispersed within the CMK-3 channels as small nanoparticles. CMK-3 still had a large surface area after copper (II) oxide was incorporated. T... |
