针对“水热法制备二氧化锡纳米材料”实验教学中存在的问题进行了改进。利用平行反应仪代替传统的水热反应釜,在反应条件明确、可控的同时提高了实验效率;将透射电子显微镜等大型分析仪器引入实验中对实验产品进行表征,让学生在更加直观地了解纳米材料的形貌与结构的同时自行设计和优化实验环节,培养和提高了学生的基本操作技能、创新意识及综合实践能力,取得了良好的教学效果。
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.
