Si基AAO模板法制备尖晶石型ZnAl2O4纳米结构

以Si基AAO为模板,以Zn和C粉作蒸发源,通过化学气相沉积法,在不同的温度下反应得到了不同的ZnAl2O4纳米结构.对样品的形貌和成分结构进行了分析.扫描电镜结果显示,在800℃获得的ZnAl2O4样品表面仍保留着AAO模板的孔洞结构.而XRD结果表明,在700,800,900℃下获得的样品都出现了ZnAl2O4衍射...

Prepared Photocatalytic of Spinel-type ZnAl2O4 Using AAO as A Template on Si Substrate

ZnAl₂O₄ composite structure was fabricated using Zn and C powers by CVD method at different temperature. Structure and optical properties of the composite structure were investigated using scanning electron microscopy (SEM) and X-ray diffraction (XRD). SEM results indicated that the sample of ZnAl₂O₄ structure prepared at 800 ℃ remained the regular pore structure of AAO template. The XRD patterns demonstrated that the diffraction peaks of the ZnAl₂O₄ appeared at the reaction temperature of 700, 800, 900 ℃. That indicated the ZnAl₂O₄ structures were obtained successfully. The optimum temperature for CVD method fabricated ZnAl₂O₄ nanostructure was 800 ℃ by the SEM and XRD results.
