Abstract

Abstract:

The BaTiO₃?TiO₂ composites were prepared by using hydrate barium hydroxide (Ba(OH)₂·8H₂O) and titanium dioxide (TiO₂) as raw materials with soft chemical hydrothermal method at 120 ℃ and different Ba/Ti molar ratios.The structure of the prepared composites with different Ba/Ti molar ratios was analyzed by X?ray diffraction (XRD),scanning electron microscopy (SEM),and UV?visible absorption spectroscopy (UV?Vis),the degradation effect of the complex on the simulated degradation pollutant,rhodamine B (RhB) was investigated.The results indicate that the BaTiO₃?TiO₂ composites obtained at a Ba/Ti molar ratio of 0.50 have an excellent catalytic effect for the degradation of rhodamine B (RhB) during the simulation of dye wastewater degradation.Meanwhile,more active sites formed at the Ba/Ti molar ratio of 0.50, which facilitated the photocatalytic reaction.

摘要：

以八水合氢氧化钡(Ba(OH)₂·8H₂O)、二氧化钛(TiO₂)为原料，采用软化学水热的制备方法，在120 ℃的温度下，通过调控不同n（Ba）/n（Ti）合成了BaTiO₃?TiO₂复合体。通过X射线衍射（XRD)、扫描电镜（SEM）、紫外?可见吸收光谱（UV?Vis）等测试手段，研究了不同n（Ba）/n（Ti）条件下所得到的复合体的结构，并考察了复合体对模拟降解污染物——罗丹明B（RhB)的降解效果。结果表明，当n（Ba）/n（Ti）=0.50时，BaTiO₃?TiO₂复合体对罗丹明B的降解率最大，催化效果最好；同时，n（Ba）/n（Ti）=0.50时，所形成BaTiO₃?TiO₂复合体的活性位点最多，有助于光催化反应的进行。
