中文摘要：

以自制碳纳米管（CNTs）为载体,制备了负载型催化剂Ce-Ti-Ox/CNTs,并进行了TEM及XRD表征。以所得样品为催化剂应用于东都风化煤降解制备腐殖酸的研究,探讨了不同铈钛摩尔比及紫外灯照射时间对风化煤降解制备腐植酸产率的影响,结果表明：铈钛相互掺杂及外灯照射,使得腐植酸的产率得到明显提高,最佳铈钛摩尔比为0.03/1,最佳照射时间为50 min。

英文摘要：

Ce-Ti-Ox/CNTs was prepared by certain methods using self-made CNTs as support. Properties of the sample was characterized by means of TEM and XRD techniques. The sample was used as catalyst in the nitric acid oxido- degradation of Dongdu weathered coal. The influences of different molar ratioes of Ce and Ti and the irradiation time of UV lamp to the preparation of hiumic acid were studied. The results showed that doping Ce and Ti and irradiating with UV lamp could improve the production of hiumic acid obviously, and the operating parameters were optimized as molar ratioes of Ce and Ti of 0.03 ： 1 and irradiation time of 50 min.
