| Abstract: | Modern instruments such as transmission electron microscope （TEM） are introduced into the synthesis experiment to improve the experimental teaching of ＂ hydrothermal synthesis of SnO2 nanomaterial＂. The parallel reactions instrument take place of the traditional autoclave making reaction conditions clear and controllable. The efficiency is improved as well. Characterization of the products＇ morphology and phase made students know more about what they fabricated and also increased their fundamental technical ability, creative consciousness and the comprehensive practical ability. The teaching effects are improved. |
