摘　　要：构建一种简单液相法合成ZnO/Cu_2O异质结光催化材料的开放式实验教学模式.利用开放实验平台,使用简单液相法合成ZnO/Cu_2O异质结光催化材料,采用扫描电子显微镜及能谱仪对材料的形貌及成分进行表征,并在可见光条件下对其进行光催化降解罗丹明B实验.实验结果表明:ZnO/Cu_2O复合材料的光催化性能要优于纯ZnO的光催化性能.新的教学模式以学生为中心,可充分调动学生的科研兴趣,培养学生的实践能力、自主思考能力和创新能力.An open experimental teaching model for synthesis of ZnO/Cu2O heterojunction photocatalytic materials by simple liquid-phase method is constructed.Through open experimental platform,the ZnO/Cu2O heterojunction photocatalytic material is prepared.The morphology and composite of the material are characterized by scanning electron microscopy and energy dispersive spectrometer,respectively.In addition,the degradation of rhodamine B under visible illumination is conducted.The results show that the photocatalytic activity of ZnO/Cu2O material is better than that of pure ZnO.The new teaching model takes students as the center,fully arouses the students’ interest in scientific research,and cultivates the students’ practical ability,independent thinking ability and creative ability.
