    摘要:

    以Ti(OBu)4為鈦源、三聚氰胺為氮源，通過(guò)溶膠-凝膠和高溫煅燒兩步法制備了高活性可見(jiàn)光光催化劑TiO2/g-C3N4。利用X射線(xiàn)粉末衍射（XRD）、透射電子顯微鏡（TEM）和紫外-可見(jiàn)漫反射光譜（UV-vis diffuse reflectance spectra ）等手段對(duì)其進(jìn)行了表征。結(jié)果表明：TiO2鑲嵌在石墨相的g-C3N4中，并與g-C3N4構(gòu)成TiO2/g-C3N4復(fù)合材料。由于TiO2與g-C3N4的協(xié)同作用，擴(kuò)大了TiO2/g-C3N4的可見(jiàn)光吸收范圍和強(qiáng)度，因而其具有很好的可見(jiàn)光光催化性能。

    Abstract:

    A highly active photocatalyst TiO2/g-C3N4 was facilely synthesized by a facile two-step method, sol-gel method and calcination using Ti(OBu)4 as Ti source and melamine as nitrogen source. The structural and morphological properties of the resultant photocatalysts were characterized. The results showed that TiO2/g-C3N4 was formed and TiO2 was beset with graphite-like carbon nitride of layer structure. TiO2/g-C3N4 exhibited obviously enhanced visible light photocatalytic activity, and the degradation efficiency of Methylene blue (MB) reached 94.46% after irradiation for 1h, which was much higher than that of g-C3N4 and TiO2. The improved photocatalytic activity of TiO2/g-C3N4 was attributable to its wide spectrum responsive range, strong visible light adsorption capability, and the synergistic effect between TiO2 and g-C3N4. The mechanism of photocatalytic reaction was discussed.
