摘　　要： 结合前期的研究成果,设计了一个以α-Fe2O3的合成、表征及催化性能研究为主线的研究型实验,学生在教师的引导下查阅文献,设计实验方案,运用多种实验技术表征产品.学生通过对实验数据和表征结果的分析,确定各因素对实验结果的影响,从而优化实验方案,最后以科研论文的形式撰写实验报告,并且通过答辩进行讨论交流.该实验模式的实施有利于高素质人才的培养. A research-oriented experiment was designed on the basis of previous study. The experiment took the synthesis, characterization and the catalytic performance of a-Fe2 O3 as the main line. With the guide of the teacher, students reviewed literature, designed experiment program, and tested products using many experimental technologies. By analysis of the experimental data and characterization results, the factors affecting success of the procedure were identified,and the optimum experimental schemes were reached. Finally, Students wrote experiment reports in the form of science paper and communicated with others through thesis defense. This experimental mode is helpful to cultivate talents with high quality.
