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(C_3N_4)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/C_3N_4)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/C_3N_4复合材料的光催化活性,结果表明:RGO 的引入显著提高了C_3N_4的光催化活性,且6.0% RGO/C_3N_4复合物的光催化活性最高,可能的原因是RGO 具有优良的接受和传导电子性能,抑制了C_3N_4光生电子-空穴的复合机率,进...

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 sample...
