摘要:本文以六水硝酸锌(Zn(NO_3)_2·6H_2O)和2-甲基咪唑为原料,在不同溶剂条件下(甲醇、乙醇和水)制备前驱体金属有机框架化合物ZIF-8。接着,采用热重(TG)、红外光谱(FTIR)、X射线粉末衍射(PXRD)、紫外-可见漫反射光谱(UV-vis DRS)和扫描电镜(FE-SEM)等手段对前驱体ZIF-8和目标产品Zn O进行了表征。以亚甲基蓝为模拟污染物,考察了不同溶剂可见光下制备Zn O的光催化性能及催化剂的稳定性。结果表明:在溶剂水条件下制备的Zn O的光催化性能最好,且具有一定的稳定性。
A series of Metal-Organic Frameworks Zeolitic Imidazolate Framework-8(ZIF-8)were prepared by Zn(NO3)2?6H2O and2-methylimidazole by different solvents(methanol,ethanol and water).Then,the precursor ZIF-8and ZnO product were charac-terized and analyzed by thermogravimetry(TG),infrared spectrum(FTIR),powder X-ray diffraction(PXRD),ultraviolet-visible dif-fuse reflection spectrum(UV-vis DRS)and field emission scanning electron microcopy(FE-SEM).The photocatalytic activity was e-valuated by decolorization of methylene blue and the stability of catalysts were studied.The results show that ZnO(water)exhibit good photocatalytic activity for dye degradation under visible-light and show good stability toward photocatalysis.
