氨硼烷催化水解制氢综合实验设计

Comprehensive Experiment Design of Hydrogen Production by Catalytic Hydrolysis of Aminoborane

根据物理化学实验教学的需求,设计了氨硼烷催化水解制氢综合探索性实验。采用化学还原法制备了新型镍硼纳米催化剂,将其用于氨硼烷水解催化反应,考察催化剂用量和温度对反应速率的影响,并根据阿雷尼乌斯公式测定反应的活化能。通过探索性操作完成整个实验流程,学生不仅可以掌握催化剂的化学还原法制备技术,还可以强化和巩固利用化学动力学知识分析处理实验数据的能力。

In order to satisfy the needs of physical chemistry experiment teaching,a comprehensive exploratory experiment of hydrogen production by catalytic hydrolysis of aminoborane is designed based on the scientific hot spots and the authors’research field.A new type of nickel-boron nano-catalyst is prepared by chemical reduction method and used in the catalytic reaction of aminoborane hydrolysis.The effect of catalyst dosage and temperature on the reaction rate is investigated.The activation energy of the reaction is determined according to Arrhenius formula.Through exploratory operation and completion of the whole experimental process,students can not only master the chemical reduction preparation technology of catalysts,but also strengthen and consolidate the ability to analyze and process experimental data using chemical kinetic knowledge.
