摘要
二氧化碳作为常见气体存在于大气中,有价廉易得、储量丰富及无毒等优点。近年来,随着二氧化碳的过度排放,地球生态已逐渐恶化,如何简单高效地转化二氧化碳气体,降低碳排放,是二氧化碳高排放行业迫切需要关注的重点问题。将二氧化碳转化为高价值化学品,创新地拓宽二氧化碳转化领域,正成为越来越多科研人员的研究课题。二氧化碳分子的活化是对其进行化学转化的前提,本文根据不同的催化转化机理,大致介绍了羧酸、羰基化合物、甲醇、酯等不同转化产物的合成方法。通过催化还原将二氧化碳转化为低值化学品,为实现碳循环提供了可行的办法。
Carbon dioxide was a common gas in the atmosphere,which has the advantage of being advantage of cheapness,abundant reserves,and non-toxic.In recent years,the earth’s ecology had gradually deteriorated with the excessive emission of carbon dioxide.It was worthwhile to study how to efficiently convert carbon dioxide gas and reduce carbon emissions,as it had become a key issue in high-emission carbon dioxide industries.Converting carbon dioxide into high-value chemicals and innovatively broadening the field of carbon dioxide conversion are increasingly becoming research topics for researchers.The activation of carbon dioxide molecules was a prerequisite for their chemical conversion.Based on different catalytic conversion mechanisms,this paper roughly introduced the synthesis methods of different conversion products such as carboxylic acids,carbonyl compounds,methanol,and esters.Catalytic reduction of carbon dioxide into low-value chemicals offered a feasible method for realizing carbon cycling.
