以静电纺丝法制备TiO2纳米纤维(TiO2(NF))和TiO2-氧化石墨（GO）复合纳米纤维（TiO2(NF)-GO）加氢脱硫催化剂的载体，采用等体积浸渍法制备NiMo/TiO2(NF)和NiMo/TiO2(NF)-GO催化剂，运用N2吸附-脱附、X射线衍射、XPS、TEM、Raman光谱和NH3程序升温脱附等表征手段对载体和催化剂进行表征分析，并考察掺杂不同含量 GO 对催化剂加氢脱硫性能的影响。实验结果表明，当 GO/TiO2(NF)质量分数为0.5%时，复合载体的中强酸增加得最多，在温度280℃、氢气分压2.0 MPa、体积空速4 h?1，氢油体积比400相当温和条件下，对应的催化剂表现出优异的加氢脱硫性能。

Novel TiO2 nanofibers(NF) and TiO2(NF)-graphene oxide (GO) supports were prepared by electro-spinning, and NiMo/TiO2(NF) and NiMo/TiO2(NF)-GO catalysts were obtained by incipient impregnation. The properties of supports and catalysts were characterized by N2 absorption-desorption, X-ray diffraction, SEM, TEM, Raman spectra and NH3-TPD. The effect of different loading of GO was investigated. The results showed that when the mass fraction of GO/TiO2(NF) was 0.5%, the intermediate-strong acid sites increased to the maximum. Under the mild conditions of 280℃, 2.0 MPa, LHSV 4 h?1 and H2/feed ratio 400 (vol), the corresponding catalyst exhibited the excellent HDS performance.
