The National Chemical Experiment Teaching Center of Nanjing University reformed the chemistry laboratory teaching based on the “3-to-3” undergraduate talents cultivation mode put forward by Nanjing University. The “academic talent training” laboratory course was reformed, the academic-orientated laboratory course was strengthened, and the “employment talent training” laboratory course was constructed. During the past 10 years, great progress has been made based on these reforms.

An experiment “Doping and Photocatalytic Performance of TiO2 Nanopowder” was performed in inorganic comprehensive laboratory for Boling Class of Nankai University. After the dopant precursors and corresponding contents were determined by the students, different elements doped TiO2 powders were prepared by sol-gel method, and characterized by scanning electronic microscopy, transmittance electronic microscopy, powder X-ray diffraction and UV-Vis diffuse reflectance spectroscopy. The photocatalytic performances of the prepared catalysts were monitored by the degradation of methyl orange as the simulated wastewater to select the superior ones for photocatalytic water splitting test. Through this comprehensive experiment related to research frontier, the students in Boling Class can obtain basic research training and their scientific literacy can be improved.

Elemental chemistry is an important part of inorganic chemistry. The study on the properties and reaction rules of inorganic compounds through experimental methods can make the traditional descriptive teaching a threedimensional teaching that is easy to be received by students. This experiment includes the synthesis of simple inorganic compounds and the utilization of temperature-programmed reduction technique (TPR) to investigate the redox properties of those inorganic compounds. The TPR technique can directly reflect the reduction process of the samples and provide the qualitative information of the reduction ability from the peak location, quantitative information of the reduced species from the peak intensity, and the interaction between the components. The TPR technique can be easily applied in college teaching for chemical laboratory courses.

: An instrumental analysis experiment “Diversified assembly and application of optic fiber spectrometer” is recommended for undergraduates. UV-Vis spectrometer, molecular fluorescence spectrometer, near-infrared spectrometer, Raman spectrometer, and laser-induced fluorescence spectrometer can be assembled using light source, fiber, and charge-coupled devices detector, etc. Through the practice of this experiment, the traditional optical experiment is extended. It is helpful for students to cultivate the professional skills and abilities comprehensively by hands-on assembling the optical instruments.

: Intelligent classroom based on modern information technology has become the right-hand man in teaching, but its application in basic chemistry is still in its infancy. The practical process and availability of intelligent classroom have been explored from two aspects of the theoretical knowledge and experiment skills in analytical chemistry teaching, which aims to guide students to build a systematic knowledge system and achieve a complete learning under the fragmented teaching model. Furthermore, students can obtain scientific consciousness and standard operation skills within limited class hours.

: In this experiment, molecularly imprinting polymers (MIP) electrodes with specific recognition ability of bisphenol A (BPA) were prepared by electropolymerization method. O -phenylenediamine was used as the polymeric monomer and BPA as the target molecule. The MIP electrodes were characterized by differential pulse voltammetry and quartz crystal microbalance. Results showed that the electrodes had highly specific recognition ability for BPA. In comparison with the non-imprinting polymers electrode, the recognition ability of MIP was improved by one order of magnitude. 100-fold concentration of atrazine or 17 β -estradiol only altered the signal by one-tenth, indicating high selectivity of BPA-MIP electrode in complex matrix. In addition, this experimental design allows flexible target selection. Therefore, after changing the target molecules, the similar MIP electrode could be also successfully prepared by the same method. This experiment allows students to design experiments by themselves. And students can gain an in-depth understanding of the interaction between molecules, and experience the process of designing materials at the molecular level.
