光催化生产双氧水实验教学设计

Experimental Teaching Design of Hydrogen Peroxide Production by Photocatalysis

在综合化学实验教学过程中,教学团队引入绿色化学的理念,设计了一个环境友好型的综合性实验——氮化碳光催化生产双氧水及含量检测。通过氮化碳(g-C_(3)N_(4))光催化剂合成、光催化生产双氧水以及双氧水含量计算,使学生了解光催化这一化学前沿领域,同步强化学生的实验动手能力以及分析、解决科学问题的能力,激发学生对于化学学习的积极性和热情,产生了良好的教学效果。

In the teaching process of comprehensive chemistry experiment,the teaching team introduced the concept of green chemistry and designed an environmentally friendly comprehensive experiment,hydrogen peroxide production by photocatalysis and its content detection including the synthesis of carbon nitride(g-C_(3)N_(4))photocatalyst,photocatalytic production of hydrogen peroxide,and calculation of hydrogen peroxide content.From this experiment,students could understand the cutting-edge field of photocatalysis in chemistry,and simultaneously enhanced their experimental and hands-on abilities,as well as their ability to analyze and solve scientific problems.Thereby a good teaching effect was obtained.
