Preparation of AgVO_(3)/g-C_(3)N_(4) Composite Photocatalyst and Its Photocalytic Activity

使用水浴沉淀法制备AgVO_(3)/g-C_(3)N_(4)复合材料,对其进行紫外漫反射光谱(UV-vis DRS)、傅里叶变换红外光谱(FT-IR)、扫描电子显微镜(SEM)和X射线衍射(XRD)等表征。通过降解RhB情况评估复合材料光催化性能。实验改变AgVO_(3)比例,探究AgVO_(3)含量对复合物光催化性能的影响。结果表明,2%AgVO_(3)/g-C_(3)N_(4)具有最好的光催化活性,40 min降解RhB高达94.8%。

In this paper,a precipitation method was used to prepare AgVO_(3)/g-C_(3)N_(4) composite material,which was subjected to ultraviolet diffuse reflectance spectroscopy(UV-vis DRS),Fourier transform infrared spectroscopy(FT-IR),scanning electron microscope(SEM)and X X-ray diffraction(XRD)and other characterization.The photocatalytic performance of composite materials was evaluated by the degradation of RhB.The experiment changed the proportion of AgVO 3,and explored the influence of AgVO 3 content on the photocatalytic performance of the composite.The results showed that 2%AgVO_(3)/g-C_(3)N_(4) had the best photocatalytic activity,and the degradation of RhB reached 99.9%in 40 minutes.
