摘要
用柠檬酸络合法合成了纳米钙钛矿型LaCoO3,复合氧化物,并在其悬浮体系中对CO32-进行光催化还原实验,测定催化剂的用量、反 应时间、溶液pH值及CO32-浓度等条件对还原产物甲酸、甲醛产量的影响。结果表明,纳米LaCoO3具有光催化还原活性,在其悬浮体系中 CO32-可以被还原为甲酸、甲醛等有机基本原料。
Perovskite-type LaCoO3 oxide was prepared by citric acid complex. The experiments of photocatalysed reduction of CO32-were made in its aqueous suspension system. The effects of amount of catalyst, reaction time, pH value and concentration of CO32-on the yield of reduced products formate and formadehyde were studied. The results show that LaCoO3 has photocatalytic reduction activity and CO32- in the system can be reduced to the basic organic materials formate and formadehyde, which is a new way to exploit CO2 resources.
