摘　　要：本文以十二烷基磺酸钠为模板剂,钛酸四丁酯为钛源,采用水热法制备了介孔TiO2光催化剂和不同摩尔比的Nd掺杂介孔TiO2光催化剂,通过X-射线衍射(XRD)分析、N2吸附-脱附和孔径分布(BET和BJH)等对其进行表征,并且以甲基橙溶液为目标污染物,考察了所制备样品光催化性能。研究表明,所制备样品均为锐钛矿型结构TiO2晶体,H2型孔结构,均具有较强的光催化性能,样品1%Nd-TiO2光催化性能最强,在紫外光条件下40min内甲基橙溶液的降解率达到了98.4%。This experiment by sodium dodecyl sulfate as the lemplate agent and tetrabutyltitanate as titanium source,using the hydro thermal preparation of mesoporous titanium dioxide and different mole ratio of Nd doped mesoporous TiO2 photocatalyst,by X-ray diffraction(XRD) analysis,N2 adsorptionechoing off(BET and BJH) on the pore size distribution were characterized,and methyl orange solution as the goal pollutant,sample preparation by photo catalytic properties are investigated.Research shows that the preparation of samples for anatase type structure,H2 type of pore structure,have strong photo catalytic performance,sample 1% Nd-TiO2 photocatalytic performance is strongest,under the condition of UV light within 40 minutes the degradation of methyl orange solution rate reached 98.4%.
