摘要
以硝酸银、磷酸钠和醋酸钙为原料,氧化石墨烯(GO)为调节剂,常温下采用共沉淀法合成了磷酸银/羟基磷灰石/氧化石墨烯(Ag3PO4/HAP/GO)复合物,利用X-射线粉末衍射仪(XRD)及扫描电子显微镜(SEM)对样品的形貌和结构进行表征和分析.并以亚甲基蓝(MB)为模拟污染物,评估其光催化性能.结果表明,在模拟日光照射下Ag3PO4/HAP/GO催化降解MB的速率分别是单体Ag3PO4、HAP的 12 和 64 倍.尽管Ag3PO4/HAP/GO和Ag3PO4/GO速率差别不大,但是HAP的引入大大降低催化剂的成本,为Ag3PO4/HAP/GO的广泛应用提供了前置条件.
Abstract
The composite of silver phosphate/hydroxyapatite/grapheme oxide(Ag3PO4/HAP/GO)was syn-thesized at room temperature using silver nitrate,sodium phosphate,and calcium acetate as raw materials with co-precipitation method.During the preparation process,graphene oxide(GO)worked as a regulator.The mor-phologies and structures of the samples were characterized and analyzed by X-ray powder diffraction(XRD)and scanning electron microscopy(SEM).Methylene blue(MB)was used as a simulated pollutant to evaluate the photo-catalytic performances of the prepared composites.The results show that the catalytic degradation rate of MB by Ag3PO4/HAP/GO is12 and 64 times higher than that of Ag3PO4 and HAP,respectively,under the simu-lated sunlight irradiation.Although there is not much difference in the rates between Ag3PO4/HAP/GO and Ag3PO4/GO,the introduction of HA greatly reduces the cost of the catalyst and provides a prerequisite for the widespread application of Ag3PO4/HAP/GO.
