生物碳制备及其锌空气电池应用综合实验设计

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.
