通过溶胶-凝胶法合成了上转换发光材料Er3+:V0.01Y2.99Al5N0.01F0.01O11.98(Er:YAG),然后利用水热法合成了BiPO4,再利用高温煅烧法合成了Er:YAG/BiPO4/Pt复合物光催化剂.通过使用X-射线粉末衍射仪(XRD),扫描电子显微镜(SEM),透射电子显微镜(TEM),光致发光光谱(PL)和上转换发射光谱对样品的组成、形貌及光学特征进行了表征.此外,还研究了不同甘油添加量、Er:YAG和BiPO4的摩尔比例和复合温度及光催化剂的循环使用次数对Er:YAG/BiPO4/Pt复合物光催化剂活性的影响.实验结果显示Er:YAG/BiPO4/Pt复合物光催化剂具有高的光催化活性和较好的稳定性,它可以作为一种高效的光催化剂用于污水中有机污染物的处理. |

In this study, the up-conversion luminescence material Er3+:V0.01Y2.99Al5N0.01F0.01O11.98 was synthesized by the sol-gel method, and then BiPO4 was synthesized by a solvothermal method. Finally, the Er3+:V0.01Y2.99Al5-N0.01F0.01O11.98 (Er:YAG)/BiPO4/Pt composite photocatalyst was prepared by the high-temperature calcination method. The prepared samples were characterized by X-ray diffractometer (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) spectra and up-conversion emission spectra. In addition, the effects of different glycerin additive amount, Er:YAG and BiPO4 molar ratio and compound temperature, cycle number of photocatalyst on the photocatalytic activity of Er:YAG/BiPO4/Pt composite photocatalyst. Experimental results show that the Er:YAG/BiPO4/Pt composite photocatalyst have high photocatalytic activity and good stability, it can be used as a high-efficient photocatalyst to treat the organic pollutants in wastewater. |
