摘要
创新实验是学生掌握科学知识,了解科学研究过程及方法的最直观、最有效的途径,能够显著提高学生的科学素养.利用学校科研平台,开发设计了一种水热法合成Ni-Co层状双金属氢氧化物(Co-Ni LDH)并对其电催化产氧性能进行研究的创新实验.学生在文献调研的基础上制定详细的实验方案,然后使用水热法合成电催化材料,并对其进行相关测试表征,综合评价材料的电催化析氧(OER)性能.教学实践表明,这种全新的教学模式充分发挥了学生的主体作用,深化了学生对电解水领域知识的认知,让其掌握了基本的科研步骤,在激发学生科研兴趣的同时,拓展了学生的创新思维,提高了学生科学素养.
Innovative experiments are the most effective way for students to get scientific knowledge and understand the steps and methods of scientific research.In this paper,an innovative experiment was designed to synthesize Ni-Co layered double hydroxide(Co-Ni LDH)by hydrothermal method and the electrocatalytic oxygen evolution reaction(OER)performance of the samples was investigated on the scientific research platform of our university.After literature research,the students made a detailed experimental plan,and then synthesized Ni-Co LDH electrocatalytic materials by hydrothermal method.Based on the test and characterization of the samples,the students made a comprehensive evaluation of the OER performance of the materials.The teaching practice showed that this new teaching mode was beneficial to highlight the main role of students,deepen their cognition of the knowledge in the field of water electrolysis,and enabled them to master the basic scientific research steps.It not only stimulated students’ interest in scientific research,but also expanded their innovative thinking and improved their scientific literacy.
