摘要
无机化学实验是培养应用化学专业本科生发散性思维和辩证唯物主义世界观的关键训练环节之一,鉴于纳米无机材料在新能源领域的广泛应用,结合本科生学习特点,本文以典型的无机材料合成教学内容为例,首先设计碳热还原法和液相还原法合成Ir/TiC催化剂,通过X射线粉末衍射仪、透射电镜仪器对催化剂晶型和形貌进行表征分析,之后应用电化学工作站和电解槽系统评价了催化剂的性能。设计成综合化学实验教学,不仅增强学生无机材料制备分析能力的同时,而且助力学生与科学前沿研究成果“接轨”,提升科学素养。
The experiment of inorganic chemistry is one of the key training links for undergraduates mastering the theoretical knowledge of inorganic chemistry,which can cultivate students'divergent thinking and dialectical materialism world view through experimentation.In view of the wide application of nano-inorganic materials in the field of new energy,a typical inorganic material synthesis teaching content is taken as an example to design a carbon-thermal reduction method and liquid phase reduction method to synthesize TiC materials,and as a carrier supported Ir in the electrocatalytic oxygen evolution reaction application.The crystal shape and morphology of the catalyst were characterized by X-ray powder diffractometer and transmission electron microscopy,and then the performance of the catalyst was evaluated by electrochemical workstation and electrolyzer.This experiment plays a significant role in exercising students'ability to prepare inorganic materials,understanding the scientific frontier,and improving scientific literacy.
