A nano-composite consisting of TiO2-CNT was prepared via the sol-gel technique by using titanium n-butoxide along with carbon nano-tubes (CNTs) followed by calcination at 450 degrees C. Spectral analysis reveals that the TiO2 formed was present on the carbon in anatase form. The effect of adsorption was investigated in an aqueous solution of procion blue dye in a darkroom and the photochemical reaction in aqueous suspensions of titania composite under UV illumination. The reaction was studied by monitoring the discoloration of dye via employing a UV-Visible spectrophotometeric technique as a function of irradiation time. The composite catalyst was found to be efficient in the photodegradation of the dye.
通过溶胶-凝胶技术，使用正丁醇钛和碳纳米管（CNT）制备了一种由TiO₂-CNT组成的纳米复合材料，随后在450℃下进行煅烧。光谱分析表明，形成的TiO₂以锐钛矿形式存在于碳上。在暗室中对活性艳蓝染料水溶液中的吸附效果进行了研究，并对二氧化钛复合材料水悬浮液在紫外光照下的光化学反应进行了研究。通过使用紫外可见分光光度技术监测染料的褪色情况，研究了该反应随照射时间的变化。发现该复合催化剂对染料的光降解具有高效性。
