摘要: 用高温煅烧法制备了NixZn1-xFe2O4和g-C3N4,再用液相自组装法合成NixZn1-x-Fe2O4/g-C3N4复合材料。利用X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、紫外-可见漫反射光谱(DRS)和氮气吸附-脱附等手段对产物进行了表征;光催化实验结果表明,可见光下25%Zn5Ni05Fe05O4/g-C3N4复合材料具有最高的产氢效率,未加光敏剂EY时为2668 mmol·g-1,加入光敏剂EY时提高到了37313 mmol·g-1。

Abstract: NixZn1-xFe2O4 and g-C3N4 were synthesized by high temperature calcination and NixZn1-xFe2O4/g-C3N4 composites were synthesized using a liquid phase self-assembly method. The samples were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy(DRS) and N2 adsorption-desorption measurements. The photocatalytic experiments showed that 25%Zn5Ni05Fe05O4/g-C3N4 exhibit the highest activity for hydrogen production under visible light irradiation.The hydrogen evolution amount with and without photosensitizers (Eosine Y, EY) is 2668 mmol·g-1 and 37313 mmol·g-1, respectively.
