摘要
以磷钨酸(H_3PW_(12)O_(40))和氧化石墨烯(GO)为原料,采用水热方法通过改变反应温度制备H_3PW_(12)O_(40)/GO复合材料。通过傅里叶红外光谱(FT-IR)、X-射线粉末衍射(XRD)、扫描电子显微镜(SEM)和透射电镜(TEM)对合成的材料进行表征及形貌分析,以H_3PW_(12)O_(40)/GO复合材料作为光催化剂催化降解甲基橙、结晶紫、刚果红染料溶液,结果表明:H_3PW_(12)O_(40)/GO复合材料降解甲基橙溶液脱色率达到85.62%,降解结晶紫溶液脱色率达到89.78%,降解刚果红溶液脱色率达到82.62%。
The H3PW12O40/GO composite photo-catalysts were successfully fabricated phosphotungstic acid(H3PW12O40)and graphene oxide(GO)via changing the temperature of the hydrothermal.The composites were characterized by X-Ray Powder Diffraction(XRD),Fourier transform infrared spectroscopy(FT-IR),and surface morphologies were obserred by scanning electron microscope(SEM)and transmission electron microscope(TEM).The photocatalytic degradation performance of H3PW12O40/GO composite was investigated using methyl orange,crystal violet and congo red as model reactions.The results of the experiment show the degradation rate of methyl orange was85.62%,the degradation rate of crystal violet was 89.78%and the degradation rate of congo red was82.62%.
