摘要
以提升化学核心素养为目标,设计了二维镍铁类水滑石电催化剂用于全解水反应的综合实验。通过共沉淀法制备了镍铁水滑石,表征了XRD、FT-IR、SEM、BET、XPS,并进一步探究其全水解性能。该实验案例旨在让学生了解电催化剂的制备过程,理解全解水产氢、产氧的反应机理,掌握三电极与两电极体系中电化学性能的测试方法。该综合实验将化学核心素养贯穿于实验预习、电催化剂制备、物化性能表征、电化学性能测试、结果与讨论的整个实验设计与实践过程中。该综合实验有助于提高学生对能源与环境的保护意识,增强绿色化学理念,适用于中学与大学化学实验教学。
To cultivate the core accomplishment of chemistry,a comprehensive experiment of 2D NiFe hydrotalcite electrocatalyst was designed for overall water splitting.NiFe hydrotalc was prepared by coprecipitation method,characterized by XRD,FT-IR,SEM,BET and XPS,and further investigated its overall water splitting performance.The experimental case aims to let students understand the preparation process of electrocatalysts,understand the reaction mechanism of hydrogen and oxygen production,meanwhile master the measurement method of electrochemical performance in three-electrode and two-electrode systems.The chemistry core literacy runs through the whole process of the experiment,including experimental preview,electrocatalyst preparation,physicochemical performance characterization,electrochemical performance testing,results and discussion.This comprehensive experiment is helpful to improve students' safety awareness of energy and environment,enhance the concept of green chemistry,and is applicable to chemistry experiment teaching in middle schools and universities.
