摘　　要：以溶胶-凝胶法制备了纳米TiO2和稀土离子Eu3+、Nd3+掺杂的TiO2,并以TiO2和核黄素溶液为催化剂氙灯照射光催化深度去除油品中苯并噻吩,考察了氧化剂、双氧水浓度、核黄素浓度等工艺条件的影响.结果表明:体积浓度为25%的双氧水脱硫效果较好,当核黄素浓度达到25μg·mL-1时,脱硫率达到最高,稀土掺杂TiO2后可提高油品硫的脱除率,TiO2光响应范围向可见光拓展.Nano-TiO2 were prepared by sol-gel progress. Eu3＋,Nd3＋ were adoped to enhance the photocatalytic ac-tivity under visible light. The degradation of benzobthiophene in jet fuel was investigated by TiO2 catalyst and ribo-flavin solution under xenon lamp. The results indicate that Lanthanon into titania could efficiently extend photoactiv-ity and expand the visible light response range. The desulfurization rate was high under 25% H2 O2 volume fraction. The desulfurization rate reaches to 78. 85% using Eu-TiO2 .
