Abstract

TiO nanoparticles were synthesized using 1--butyl-3-methylimidazolium tetrafluoroborate (BMI·BF) ionic liquid and doped with non-expensive metals Cu and Fe by the sol-gel method. The new generated photocatalysts had their morphological, textural and structural characteristics analysed by scanning electron microscopy and dispersive X-ray spectroscopy (SEM/EDS), transmission electron microscopy (TEM), Brunauer-Emmett-Teller analysis (BET), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and diffuse reflectance spectroscopy (DRS). The results showed two phases by XRD analysis, anatase (majority) and rutile (minority). The SEM micrographs exposed spherical TiO NPs/BMI·BF IL and compact layers for Cu and Fe-doped TiO NPs in BMI·BF IL, the EDX confirmed only the presence of Ti, O, Fe and Cu. The BET and BJH analyses exhibited high porous TiO NPs/BMI·BF IL. The BET and BJH analyses confirmed that the pore diameter of mesoporous materials was between 12 and 16 nm with similar values for surface area (55-63 m g). The TEM images exhibited spherical shape nanoparticles with mean diameter of 20-22 nm. The DRS analysis and Tauc equation were applied to estimate the optical energy band gap of the photocatalysts. The energy band gap values of 3.1 eV, 3.32 eV, and 2.78 eV were obtained for TiO NPs/BMI·BF IL, 1% Fe-doped TiO NPs/BMI·BF IL and 1% Cu-doped TiO NPs/BMI·BF IL, respectively. Phenol photodegradation was realized using Cu and Fe-doped TiO NPs/BMI·BF IL under UV/visible irradiation and quantified by HPLC-FLD. The phenol photodegradation was investigated by different concentrations of metal-doped TiO NPs/BMI·BF IL. The new active photocatalysts 1% Cu-doped TiO NPs and 1% Fe-doped TiO NPs/BMI·BF IL exhibited high catalytic activity (99.9% and 96.8%, respectively). The photocatalysts 1% Cu and 1% Fe-doped TiO NPs/BMI·BF IL were also evaluated using industrial wastewater from the tobacco industry. The results showed 56.7% phenol photodegradation, due to the complexity of the tobacco matrix wastewater.

摘要

使用1-丁基-3-甲基咪唑四氟硼酸盐（BMI·BF）离子液体合成了TiO纳米颗粒，并通过溶胶-凝胶法用价格低廉的金属Cu和Fe进行掺杂。通过扫描电子显微镜和色散X射线光谱（SEM/EDS）、透射电子显微镜（TEM）、布鲁诺尔-埃米特-泰勒分析（BET）、傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）和漫反射光谱（DRS）对新生成的光催化剂的形态、织构和结构特征进行了分析。XRD分析结果显示有两个相，锐钛矿（主要）和金红石（次要）。SEM显微照片显示了球形的TiO NPs/BMI·BF IL以及BMI·BF IL中Cu和Fe掺杂的TiO NPs的致密层，EDX证实仅存在Ti、O、Fe和Cu。BET和BJH分析显示TiO NPs/BMI·BF IL具有高度多孔性。BET和BJH分析证实介孔材料的孔径在12至16 nm之间，表面积值相似（55 - 63 m²/g）。TEM图像显示平均直径为20 - 22 nm的球形纳米颗粒。应用DRS分析和陶氏方程来估计光催化剂的光学能带隙。TiO NPs/BMI·BF IL、1% Fe掺杂的TiO NPs/BMI·BF IL和1% Cu掺杂的TiO NPs/BMI·BF IL的能带隙值分别为3.1 eV、3.32 eV和2.78 eV。在紫外/可见光照射下使用Cu和Fe掺杂的TiO NPs/BMI·BF IL实现了苯酚的光降解，并通过HPLC - FLD进行定量。研究了不同浓度的金属掺杂TiO NPs/BMI·BF IL对苯酚光降解的影响。新型活性光催化剂1% Cu掺杂的TiO NPs和1% Fe掺杂的TiO NPs/BMI·BF IL表现出高催化活性（分别为99.9%和96.8%）。还使用烟草行业的工业废水对1% Cu和1% Fe掺杂的TiO NPs/BMI·BF IL光催化剂进行了评估。由于烟草基质废水的复杂性，结果显示苯酚光降解率为56.7%。
