综合实验设计:小麦秸秆生物质炭的制备及其锌空气电池的性能评价

Comprehensive Experiment Design:Preparation of Biomass Charcoal from Wheat Straw and Its Performance Evaluation of Zinc-Air Battery

围绕绿色可持续发展观以及“碳中和”与“碳达峰”时代背景,聚焦教育教学改革,促进科学研究对本科教学质量的提升作用,开设了生物质炭的制备及其锌空气电池性能评价综合实验。本实验以农业废弃物生物质小麦秸秆为原料,经炭化和活化手段,制备了孔结构和含氧官能团可调的生物质炭,并考察了其氧气还原和锌空气电池性能。本实验将科研热点设计为化学综合实验,内容新颖并适合本科教学,促进多学科知识内容的纵向融合,实现专业知识与科学研究热点领域的交叉,弥补了传统综合化学实验课程教学的不足。

Based on the focus on the concept of green sustainable development,the project of"carbon neutrality"and"carbon peak",and the education and teaching reform,herein,a comprehensive experiment that the controlled preparation of biomass charcoal and its Zn-air battery was designed to highlight the important role of scientific research in improving the quality of undergraduate teaching.In this experiment,biomass charcoal with adjustable pore structure and oxygen-containing functional group was prepared from agricultural waste biomass-wheat straw by carbonization and activation methods,and then employed as electrocatalyst for oxygen reduction reaction and zinc-air battery.Conversion of the research hotspot into the chemical comprehensive experiment is novel and also suitable for undergraduate teaching,which further promotes the vertical integration of multi-subject contents and realizes the cross-integration between professional knowledge and scientific research hotspot fields,and finally makes up for the shortcomings of traditional chemical experimental discipline barriers.Additionally,the combination of inquiry learning and comprehensive experiment operation is favor for improving students'comprehensive experiment skills and practical innovation ability.
