| 中文摘要 |
| 采用简单的原位沉淀法合成了可见光驱动型光催化剂Ag3PO4/g-C3N4.利用X-射线衍射（XRD）、傅里叶红外光谱（FT-IR）、扫描电子显微镜（SEM）、X-射线能谱（XPS）以及紫外可见漫反射光谱（UV-Vis DRS）等表征手段对合成的样品进行了表征.与单一的Ag3PO4和g-C3N4相比，Ag3PO4/g-C3N4复合材料对左氧氟沙星表现出了更高的催化效率.根据能带分析和自由基捕获试验，提出了Ag3PO4/g-C3N4复合材料Z型异质结构的作用机制. |
| 英文摘要 |
| The visible light-driven photocatalyst Ag3PO4/g-C3N4 was synthesized by a simple in-situ precipitation method. The synthesized samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, and UV-vis diffuse reflectance spectroscopy. Compared with that of single Ag3PO4 and g-C3N4, the Ag3PO4/g-C3N4 composite had a higher catalytic efficiency for levofloxacin. According to the energy band analysis and free radical capture experiment, the mechanism of the Z-type heterostructure of the Ag3PO4/g-C3N4 composite was proposed. |
