A comprehensive undergraduate experiment was designed based on the transformation of scientific research achievements. This experiment improved the water oxygen stability and biocompatibility of Ti₃C₂T_x nanosheets coated with polydopamine, and characterized their microstructure, composition, and electrochemical properties. Water plant sludge was used to inoculate mixed microorganisms, and the output voltage, power density, chemical oxygen demand and biological activity of the battery were tested. Using exposed carbon cloth as the control group, explore the design rules of anodes through comparative analysis of data, and encourage students to use self-made batteries to treat domestic and industrial wastewater in the experiment. Adopting a cross evaluation approach to evaluate students' experimental results, stimulating their interest in scientific research, cultivating their critical spirit and ability to solve practical problems.

In this paper, the scientific research project of zinc-air battery is transformed into a comprehensive experimental project. Based on the principle of oxygen electro catalytic reduction reaction, the heteroatom doped porous carbon derived from carbonized bean sprouts is designed. Its performance as the cathode of zinc-air battery is studied, and a multi-dimensional assessment and cross evaluation mechanism is proposed. This experiment involves materials, biology, chemistry, energy and other multi-disciplinary knowledge. It designs and regulates catalytic performance from electronic structure, mass transfer and diffusion, internal conductivity and other aspects, so that students can understand the preparation of biocarbon and the application of zinc-air battery, and master the use of microscopic and spectral characterization equipment. The feedback of scientific research achievements to teaching is conducive to stimulating students' interest in scientific research, and exercising critical thinking and scientific research innovation ability.
