本文设计及实施了SrTiO3/TiO2复合纳米光催化剂用于将CO2还原为甲酸,对于二氧化碳的固定和转化具有重要的研究价值,通过光催化还原二氧化碳探究ABO3型的纳米光催化剂对于该反应的催化效果。 首先,将他人制得的SrTiO3/TiO2复合纳米光催化剂放置于阳极。用两个量筒分别量取然后向装置中的阳极和阴极分别加入0.5mol/L 的Na2SO4溶液60ml,使用生料带封闭电解池溶液,通过预留的口向阴极鼓入CO2,阳极鼓入N2,时间持续十五分钟,然后开灯进行光催化,一小时后关灯,使用注射器取其中气体20ml,放入仪器中分析其产生氢气的量,后送往专业部门进行其液体产物的分析。 中图分类号:O614.23+2 文献标识码:A

In this paper, we designed and carry out SrTiO3/TiO2 composite nanometer photocatalysts to reduct CO2 to methanoic acid. To slove the CO2 problem required transforming CO2 into other useful or non-toxic compounds. The photocatalytic reduction of CO2 would benefit the environment and meet the need of continual development. Through reduction of CO2 by photocatalysis, making a thorough inquiry about ABO3 nanometer photocatalysts' catalytic effect. Firstly, put the above-prepared SrTiO3 composite nanometer photocatalysts into the anode. Then apply two graduated cylinders to measure out 0.5mol/L Na2SO4 60ml and add them to the anode and cathode. Finally, use the polytetrafluoroethylene film to seal the electrolyzer. Inlet CO2 into the cathode and N2 into the anode through the obligate orificium continue for about 15 minutes. After that, turn on the light, conducting photocatalysis, which lasts a hour. Afterwards, turn off the light. Then use syringe take 20ml gases among the electrolyzer and put them into the instrument to analyze the amount of H2 produced. Chinese library classification number: O614.23+2 Document code:A
