摘要

采用固态法制备了Au/SiO2、Au/TiO2、Au/Al2O3、ZnO/TiO2、ZnO/TiO2、ZnO/Al2O3和Eu2O3/SiO2、Eu2O3/TiO2和Eu2O3/Al2O3复合材料。在M/MxLy•壳聚糖//M 'xO 'y和M/MxLy•PS-co-4-PVP//M 'xO 'y (M 'xO 'y = SiO2、TiO2和Al2O3)条件下，采用壳聚糖和聚苯乙烯-co-4-吡啶(PS-co-4-PVP)两种前驱体聚合物考察了前驱体对聚合物前驱体的影响。观察了其对颗粒大小和形貌的影响。利用x射线粉末衍射、SEM-EDS图谱和HRTEM分析对复合材料进行了表征。金属纳米粒子和金属氧化物纳米粒子在基体中的分布取决于基体。期望Au、ZnO和Eu2O3在SiO2、TiO2和Al2O3基体中具有显著的光学和光催化效应。一项实验正在进行中。

Matrix Effect of Properties of Au, ZnO and Eu2O3: Silica, Titania and Alumina Matrices

The composites Au/SiO2, Au/TiO2, Au/Al2O3, ZnO/TiO2, ZnO/TiO2, ZnO/Al2O3 and Eu2O3/SiO2, Eu2O3/TiO2 and Eu2O3/Al2O3 were prepared using a solid-state method. The effect of the polymer precursors was investigated using two precursor polymers, Chitosan and Poly(styrene-co-4vinylpyridine), (PS-co-4-PVP) in the M/MxLy•Chitosan//M’xO’y as well as M/MxLy•PS-co-4-PVP//M’xO’y with M’xO’y = SiO2, TiO2 and Al2O3. The effects on the particle size and morphology were observed. The new composites were characterized using X-ray powder diffraction, SEM-EDS mapping and HRTEM analysis. The distribution of the metallic nanoparticles as well as the metal oxide nanoparticles inside the matrices depend on the matrix. Marked optical and photocatalytic effects of the Au, ZnO and Eu2O3 inside the SiO2, TiO2 and Al2O3 matrices are expected. An experiment is in course.
