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.
