Abstract: Innovative experiments are offered in chemical engineering and Technology Specialty Laboratory according to current syllabus of experiments for undergraduates.Preparation,characterization and performance evaluation of nano TiO2 photocatalyst are chosen as the first innovative experiment.During this experiment,students developed different experimental routes to prepare nano TiO2 photocatalyst after a review of related literature,and they grasped different methods to characterize the prepared photocatalyst and evaluate its performance.The students’ abilities on literature research,experimental design and organization have been improved.In addition,the ability of students’ problem finding and solving skills has been practiced by comparison,discussion and analysis of the experiment,which achieved the purpose to offer innovative experiments.
