| 摘 要： | 通过采用微波水热法和沉淀法制备了BiPO4光催化剂，并且用400 W金卤灯模拟太阳光，探究了2种方法制备的BiPO4光催化降解酸性橙Ⅱ和亚甲基蓝的活性.主要是对微波水热法制备的BiPO4进行研究.应用X射线粉末衍射(XRD)、扫描电子显微镜（SEM）、紫外-可见漫反射吸收光谱（UV-vis DRS）、傅立叶变换红外光谱（FT-IR）对催化剂进行表征.紫外漫反射图谱可以看出，微波水热法制备的BiPO4的带隙为4.05 eV，比普通沉淀法制出的样品带隙窄.其光催化降解酸性橙Ⅱ和亚甲基蓝的测试表明，微波水热法样品的降解速率常数分别是普通沉淀法的7.8倍和1.5倍，光催化活性有显著提高.

| Abstract: | In this study, BiPO4 was prepared by microwave hydrothermal and precipitation method, respectively. The photocatalytic activities of the two type of BiPO4 were evaluated by degradation of acid orange Ⅱ and methylene blue with 400 W metal halide lamps simulating as sunlight. The study mainly focuses on the BiPO4 prepared by microwave hydrothermal method. The photocatalysts were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), UV-Vis diffuse reflectance spectra (UV-vis DRS) and Fourier transform infrared spectroscopy (FT-IR). The UV-vis DRS analysis indicated that the band gap of BiPO4 prepared by microwave hydrothermal method was 4.05 eV, narrower than that of the sample prepared by precipitation method. The results of photocatalytic degradation demonstrated that the degradation rate constants of the BiPO4 prepared by microwave hydrothermal method were 6.8 and 0.5 times higher than that of those prepared by precipitation method. |
