Comprehensive Experimental Design for the Study of Green Synthesis,Characterization,and Photocatalytic Performance of ZnO
According to the requirement of"scientific research feeds teaching",a comprehensive chemical experiment was designed based on CDIO teaching concept and scientific research achievements.Firstly,conceive novel experimental system:multifunctional inorganic material ZnO is synthesized through a green pathway by extracting bioactive substances from pears as the template;Secondly,design comprehensive experimental contents which includes the synthesis,characterization and photocatalytic performance test for degrading methylene blue;thirdly,according to the contents,the teaching of the experiment will be implemented for three times,4 class hours each for sample synthesis,characterization and photocatalytic performance analysis;Finally,in order to improve teaching effect,the comprehensive experiment will be operated in three stages--before class,during class and after class,in order to achieve the knowledge objectives,ability objectives,and ideological and political objectives of the experimental project.
