The shape, the particle size and the crystal structure of the prepared nanoparticles were investigated by using TEM, XRD and FT-IR techniques. The results indicate that in certain conditions, the surfactant's bridging function improves the loading of the active components effectively, and evenly loaded CeO2/CNTs composite nanoparticles can be prepared based on Sodium Dodecyl Benzene Sulfonate. The supporting CeO2 nanoparticles were face-centered cubic crystals, with particle size of about 6.4nm. The mechanism of loading metal oxides on the surface of CNTs is discussed. On this basis, CNTs, CeO2 and CeO2/CNTs were used as the catalyst, respectively, in the nitric acid oxido-degradation of Dongdu weathered coal. The results show that CeO2/CNTs enjoy the best catalytic properties and could enhance the yield of the humic acid significantly as compared with other catalysts. Also, the prepared humic acid had the largest E4/E6 ratio, and the molecular weight of humic acid is smaller., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

articleAbstract=采用液相化学沉积法制备CeO2/CNTs纳米复合粒子，考查了表面活性剂对产物形貌的影响，采用TEM、XRD、FT-IR等手段对产物的形貌和晶相结构进行表征。结果表明，在一定条件下，表面活性剂的“桥接”作用有效地改善了活性组分的负载，以十二烷基苯磺酸钠为表面活性剂，以自制碳纳米管（CNTs）为载体，可以制备出负载均匀的CeO2/CNTs纳米复合粒子。探讨了活性组分CeO2在CNTs表面的负载机制，并在此基础上研究了所得样品在风化煤硝酸氧解制备腐植酸中的催化性能。催化结果表明，CeO2/CNTs纳米复合粒子的催化性能明显优于单纯的CeO2和CNTs的催化性能，能显著提高腐植酸的产率。,
