摘要
将高分散纳米材料制备技术引入研究型实验教学中,设计了基于简单水热法制备高分散纳米BaTiO3的综合实验,利用X射线衍射、透射电子显微镜等对材料进行组成与结构的表征;并以模拟太阳光下罗丹明B的降解评价其催化活性。该实验包含了纳米材料的制备、光催化、及材料测试表征等知识点,有利于提高学生的综合实践能力,开发学生的创新潜力。
The preparation technology of the highly dispersed nanomaterials is introduced into the researchoriented experimental teaching.A comprehensive experiment based on the simple hydrothermal method is designed to prepare the highly dispersed nano-BaTiO3.The composition and structure of the materials are characterized by the X-ray diffraction and transmission electron microscope.The catalytic activity of Rhodamine B is evaluated by the degradation under the simulated sunlight.This experiment includes the knowledge of nanomaterial preparation,photocatalysis,and material testing and characterization,which is conducive to improving students’comprehensive practical ability and developing their innovation potential.
