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