摘要
针对环境工程、制药工程和化学工程等专业设计了“Fe@C的简易合成及其催化性能调控”研究性实验。通过热处理含铁蜡烛灰制备得到碳包铁(Fe@C)催化剂。运用比表面和孔隙分析、扫描电子显微镜、高分辨透射电子显微镜和能量色散X射线光谱等手段表征了催化剂的结构和形貌。通过降解实验发现,Fe@C体系中,在0.5 g/L H_(2)O_(2)存在下,初始浓度为10 mg/L的磺胺甲恶唑(SMX)可以在120 min内被完全降解。实验通过设置多个流程,全方位地培养学生的自主学习能力,有利于提升科研素养和实践创新能力。
For majors of environmental engineering,pharmaceutical engineering and chemical engineering,a research-based experiment titled“Simple Synthesis of Fe@C and Regulation of Its Catalytic Performance”was designed.The Fe@C catalyst is prepared through a thermal treatment with the iron-containing candle soot as precursor.The structure and morphology of the catalyst are characterized by Brunauer-Emmett-Teller surface area and porosity analysis,scanning electron microscopy,high-resolution transmission electron microscopy,and energy-dispersive X-ray spectroscopy.Based on the degradation experiments,sulfamethoxazole(SMX)with an initial concentration of 10 mg/L can be completely degraded within 120 minutes with 0.5 g/L H_(2)O_(2)in the Fe@C system.The experiment improves students’self-directed learning ability in an all-round way by setting up multiple processes,and cultivates their scientific research literacy and practical innovation ability.
