| 摘 要： | 通过半封闭一步热裂解法和改进的Hummers法分别制备了类石墨氮化碳(C3N4)和氧化石墨烯(GO)，再利用光还原方法制得还原氧化石墨烯/氮化碳(RGO/C3N4)复合材料。采用X射线衍射(XRD)，场发射扫描电镜(FESEM)，X射线光电子能谱(XPS)，紫外-可见漫反射吸收光谱(DRS)，光致荧光(PL)和傅里叶变换红外光谱(FTIR)等测试技术对复合材料进行表征。以罗丹明B(RhB)为探针分子在可见光下考察RGO/C3N4复合材料的光催化活性，结果表明：RGO的引入显著提高了C3N4的光催化活性，且6.0%RGO/C3N4复合物的光催化活性最高，可能的原因是RGO具有优良的传导和接受电子性能，抑制了C3N4光生电子-空穴的复合机率，进而提高了光催化活性。

| Abstract: | The graphitic-like carbon nitride (C3N4) and graphene oxide (GO) were respectively prepared by one step semi-enclosed pyrolysis and improved Hummers method. Following the reduced graphene oxide/C3N4 (RGO/C3N4) composites were fabricated via a photo-reduction route. The as-prepared samples were characterized by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS), UV-Vis diffuse reflectance absorption spectroscopy (DRS), Photoluminescence (PL) and Fourier transform infrared spectroscopy (FTIR). The photocatalytic activity of samples was evaluated under visible light irradiation using Rhodamine B (RhB) as probe molecule. The experimental results show that the introduction of RGO could considerably enhance photocatalytic activity, and the 6.0% RGO/C3N4 composite exhibits the best photocatalytic performance. The significantly enhanced photocatalytic activity for the present composite originates from the electron-accepting and electron-transportation property of RGO, which inhibits the recombination rate of photogenerated electron-hole pairs. |
