针对目前高校开展的分析化学实验教学内容单一,侧重常规分析方法以及仪器基本原理介绍等问题,将综合性实验教学项目引入到教学中,能够增强学生独立探索、主动思考和分析问题的能力.本文设计了基于纳米TiO2光催化剂催化降解苯酚的综合性实验方案,涉及光催化降解和电化学监测的原理,以及光催化降解和电化学装置的搭建等.
Electrochemical Monitoring of Photocatalytic Degradation of Phenol Pollutants:A Recommended Comprehensive Analytical Chemistry Experiment
The scope of analytical chemistry experiments conducted in higher education institutions tends to be limited,predominantly focusing on traditional analytical methods and the fundamental principles of instruments. Introducing a comprehensive experimental teaching projects can significantly enhance students' abilities in independent exploration,proactive thinking,and problem-solving. This paper presents a detailed design for a comprehensive experiment using nano-titanium dioxide (TiO2) as a photocatalyst for the degradation of phenol pollutants. The scheme involves the principles of photocatalytic degradation and electrochemical monitoring,including the assembly of both the photocatalytic degradation and electrochemical apparatus.
