Comprehensive Chemistry Experiment Design of the Photocatalytic Production of Hydrogen Peroxide from Zirconium-based MOF
In order to strengthen the transformation of scientific research results into experimental teaching and cultivate students'scientific research and innovation ability,a comprehensive chemistry experiment on photocatalytic hydrogen peroxide(H2O2)production using metal-organic framework(MOF)materials was designed.The zirconium-based MOF photocatalyst UiO-67-(NH2)2 was synthesized by solvothermal method utilizing diamino-functionalized biphenyl dicarboxylic acid and zirconium tetrachloride.The structure and light absorption performance of as-synthesized sample were characterized by PXRD and UV-DRS.The effects of light source power,catalyst concentration and reaction time on the efficiency of photocatalytic H2O2 production were systematically investigated using blue LED as light source.Rhodamine B was used as a simulated pollutant to verify the pollutant degradation performance of the produced H2O2 solution.This comprehensive experiment involves literature review,MOF synthesis and characterization,instrumental testing,data analysis and so on.It not only deepens students'comprehensive understanding of the basic knowledge of chemistry,materials and environment,but also stimulates students'learning enthusiasm and cultivates their innovative ability.
