黄芩苷改性氮化碳的制备及光催化硫醚氧化性能研究OA
Study on Preparation of Baicalin-Modified Carbon Nitride and Its Photocatalytic Performance in Thioanisole Oxidation
采用水热法将黄芩苷与氮化碳复合,成功制备了黄芩苷改性的氮化碳材料(BA-g-C3N4).利用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)等多种表征技术,对BA-g-C3N4材料的物相结构、官能团组成及微观形貌进行了表征,并在光催化苯甲硫醚氧化反应中考察其催化活性.结果表明,以BA-g-C3N4作为催化剂,H2O2作为氧化剂,在氙灯照射条件下,目标产物苯甲亚砜的产率为65%,优于单独以黄芩苷(24%)和氮化碳(37%)为催化剂的对照反应,表明改性后的BA-g-C3N4催化活性得到明显提升.
Baicalin-modified carbon nitride(BA-g-C3N4)was successfully prepared by compounding baicalin with carbon nitride via a hydrothermal method.Various characterization techniques including X-ray powder diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR),and scanning electron microscopy(SEM)were employed to characterize the phase structure,functional group composition,and micromorphology of the BA-g-C₃N₄ material,and its catalytic activity was investigated in the photocatalytic oxidation of thioanisole.The results showed that under xenon lamp irradiation,using BA-g-C3N4 as the catalyst and H2O2 as the oxidant,the yield of the target product,methyl phe-nyl sulfoxide,reached 65%.This yield was superior to those achieved with baicalin(24%)and carbon nitride(37%)alone,indicating that the photocatalytic activity of the modified BA-g-C3N4 material was significantly enhanced.
