摘要/Abstract

摘要： 利用液相沉积技术对TiO₂反蛋白石结构材料进行表面处理, 通过在反Opal孔内表面生成一层TiO₂颗粒, 增加其有效比表面积。以降解罗丹明B为探针反应, 研究了经LPD表面处理之后的TiO₂反Opal材料的光催化活性, 考察了硼酸用量对TiO₂反Opal材料表面形貌和光催化活性的影响。结果表明LPD处理之后的TiO₂反Opal膜比未处理的膜具有更高的光催化活性, 硼酸用量在0.0183 g/mL时处理的TiO₂反Opal膜具有最高的光催化活性, 相比未处理的膜催化剂活性提高了6倍。

Abstract: The surface of TiO₂ inverse opal material was modified by Liquid Phase Deposition(LPD) method, and a layer of TiO₂nanoparticles was deposited on the inverse opal framework in order to increase the specific surface area. The photo-catalytical degradation of Rhodamine B was used as the probe-reaction to investigate the photocatalysis activity of the TiO₂ inverse opal membranes, and the influences of boric acid concentration of the LPD solution on surface morphology and photocatalysis activity of TiO₂ inverse opal membranes were investigated. The results showed that the photocatalysis activity of TiO₂inverse opal membrane modified by LPD method was improved which was about 6 times higher than that of the unmodified TiO₂inverse opal when the boric acid concentration of PLD solution was 0.0183 g/mL.

Key words: titanium dioxide, inverse opal, liquid phase deposition, photocatalysis
