摘要
本实验旨在设计一个针对本科生的大学物理实验课程,通过紫外光照射下钛氧化物对甲醛降解效率的实验,让学生深入了解光催化技术的应用背景、基本原理和实验方法。本实验采用锐钛矿型TiO_(2)、金红石型TiO_(2)和TiO三种钛氧化物材料,在紫外光照射下对甲醛进行降解,并通过测量甲醛浓度的变化来定量评估光催化降解效率。实验结果显示,锐钛矿型TiO_(2)表现出最高的降解效率,其次是金红石型TiO_(2),而TiO的降解效率最低。本实验不仅使学生掌握光催化反应的基本原理和相关科研能力,还培养了学生的实验操作技能和数据分析能力。
This experiment aims to design a university physics experiment course for undergraduate students,focusing on the photocatalytic degradation efficiency of formaldehyde by titanium oxides under ultraviolet light.The course is intended to deepen understanding of the application background,fundamental principles,and experimental methods of photocatalytic technology.The experiment utilizes three types of titanium oxide materials(anatase TiO_(2),rutile TiO_(2),and TiO)to degrade formaldehyde under ultraviolet irradiation,with the photocatalytic degradation efficiency quantified by measuring changes in formaldehyde concentration.The results indicate that anatase TiO_(2) exhibits the highest degradation efficiency,followed by rutile TiO_(2),while TiO shows the lowest efficiency.This experiment not only equips students with the basic principles of photocatalytic reactions and related research capabilities,but also cultivates their experimental skills and data analysis abilities.
