Preparation and characterization of nano-powder experiments are one of the compulsory experimental courses for materials science related field students.In this experiment,three methods including hydrothermal method,sol-gel method and sol-gel hydrothermal method are used to synthesize Al doped ZnO nanopowders, and the composition,structure,morphology and electrical performance of samples are characterized.The students can learn the general preparation technology and characterization methods of nanopowders completely and systematically,and compare the differences in morphology and performance between different synthesis methods.Consequently,the students can master the difference in synthetic mechanism between different chemical synthesis methods.
