Preparation of Doped ZnOs via Microwave and the Study of its Performance

Abstract

This dissertation aims at the preparation of the Nanometer zinc oxide doping with different elements via the method of microwave. After characterizing those pellets of prepared Nanometer zinc oxide through XRD and SEM, it illustrates that the structure of Nanometer zinc oxide is still 6 wurtzite with high purity and the size of its pellet is at an averages of 21.83nm.But different mixed elements will differentiate the pellets' diameter. Moreover, through defined the Methyl orange as the stimulating pollutant, and conducted the Catalytic performance test of the samples. And the result shows that the effect was the best when doped with only Titanium, followed by doped with both Titanium and Magnesium, and the worst was doped with only Magnesium.
