摘要:

随着在2020年提出碳达峰和碳中和目标后,减少碳排放成为我国在生态环境治理上的主要目标。二氧化碳是主要的温室气体,也是碳在空气中的主要存在形式,其在工业上具有原料易于获得、自然条件下存量大等优势。如果能回收利用空气中的二氧化碳,将其通过反应制备成可以再次利用的新物质,不仅可为有效地减少碳排放提供新的思路,也能使二氧化碳得到有效的利用。为了更加深入地研究二氧化碳的还原转化,本文阐述了目前空气中二氧化碳的主要富集方法及其还原转化思路。并根据各个研究对原料二氧化碳浓度的要求及其所采用的研究方法,包括直接转化、电催化、光催化、人工光合作用、酶法等,对近两年的研究进行了梳理和归纳。综述了其制备方法及研究成果,为还原及利用二氧化碳的研究提供进一步的参考。

Abstract:

With China's goal of carbon peak and carbon neutrality in 2020, reducing carbon emissions has become the country's main goal in ecological and environmental governance. Carbon dioxide is the main greenhouse gas and the main form of carbon in the air. In industry, it has the advantages of easy access to raw materials and large storage under natural conditions. If the carbon dioxide in the air can be recycled and prepared into new substances that can be reused through the reaction, it not only provides a new idea for effectively reducing carbon emissions, but also makes the carbon dioxide be effectively utilized. In order to further study the reduction and transformation of carbon dioxide, the main enrichment methods of carbon dioxide in air and their reduction and transformation ideas were described in this paper. According to the requirement of carbon dioxide concentration and the research methods, including direct conversion, electrocatalysis, photocatalysis, artificial photosynthesis and enzymatic method, the research in recent two years was summarized. The preparation methods and research results were reviewed, which provided a further reference for the study of carbon dioxide reduction and utilization.

Key words: carbon neutral, carbon dioxide, carbon sinks, mechanism, preparation method
