本文通过简单的一步煅烧法制备了氮缺陷g-C3N4 光催化剂材料,并通过X射线粉末衍射(XRD)、傅里叶变换红外光谱(FT-IR)、扫描电子显微镜(SEM)以及紫外可见漫反射吸收光谱(UV-vis)对所制备的光催化剂的结晶度、形貌、特征官能团和光学特性方面进行了表征分析.与此同时,通过光降解罗丹明B的实验探究了所制备的光催化剂的光催化性能.实验结果表明,当罗丹明B的质量浓度为10 mg/L,催化剂的用量为20 mg时,氮缺陷g-C3N4 具有优异的光降解性能,在20 min内对罗丹明B的光降解效率达到了 100%.这表明缺陷的引入可以有效提高原始g-C3N4 的光吸收范围,促进光生电子与空穴对的分离,增强其光催化效率.本研究为有机...

The g-C3N4 photocatalyst materials with nitrogen defects were prepared by a simple one-step calcination method,and the crystallinity,morphology,characteristic functional groups and optical properties of the prepared photocatalysts were characterized by X-ray powder diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR),Scanning electron microscopy(SEM)and Ultraviolet-visible diffuse reflectance absorption spectroscopy(UV-vis).The photocatalytic properties of the prepared photocatalysts were also investigated by photodegradation of Rhodamine B.The corresponding experimental results sho...
