摘要
设计了生物质制备以多孔炭材料为载体的铂纳米团簇用于氧还原反应的综合化学实验。生物质油茶壳在惰性气体下热解制备了生物质衍生多孔炭,并进一步通过溶剂热法在多孔炭上合成了尺寸低于5 nm的铂纳米颗粒作为氧还原的催化材料。利用透射电子显微镜(TEM)、X射线光电子能谱仪(XPS)、X射线衍射仪(XRD)和电化学旋转圆盘电极等对其进行了物理化学和电化学性质的表征。本实验的设计既符合学校的学科特色,又瞄准研究前沿,有效地补充了应用化学专业教学中缺乏的前沿领域实验的不足。另外,通过开展具有学科特色的前沿领域实验,既训练了学生掌握先进实验手段和表征方法的基本技能,提升专业素质,引导学生了解了学科前沿领域发展的基本概况,有利于学生科研素质的培养和学科的发展。
A comprehensive chemical experiment was designed on biomass-derived porous carbon loaded with platinum clusters as electrocatalysts for oxygen reduction in fuel cells.Biomass-derived porous carbon was prepared by pyrolysis of biomass camellia shell under inert gas,and platinum nanoparticles with a size of less than 5 nm were synthesized on porous carbon by solvothermal method as catalytic materials for oxygen reduction,and their physicochemical and electrochemical properties were characterized by transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS),X-ray powder diffraction(XRD)and electrochemical rotating disk electrodes.The design of this experiment not only conforms to the discipline characteristics of the school,but also aims at the research frontier,which fills the experimental gap in the lack of professional frontier fields in professional teaching.In addition,by participating in the synthesis,physicochemical and electrochemical properties of porous carbon and catalysts,it can not only cultivate students'comprehensive experimental skills,improve their scientific research literacy,guide students to understand the development of frontier fields,but also help students cultivate scientific thinking ability and stimulate students'interest in scientific research.
