Basic process of lower-order organic compound synthesis via carbon dioxide reduction induced by low temperature plasma radical reactions

二氧化碳被认为是导致全球变暖的原因，抑制二氧化碳向环境中的排放是一个紧迫的问题。此外，甲烷、甲醇等碳原子数较少的低级有机化合物是重要的可再生能源，也是重要的化工原料。在这项研究中，一氧化碳和氢的自由基反应的基本物理和化学机制，在无等离子体空间或冷等离子体中产生的分解水蒸气和二氧化碳，合成可重复使用的低级有机化合物，如甲烷和甲醇进行了研究。

Suppression of carbon dioxide emission into the environment, which has been thought as a cause of global warming, is an urgent issue. Moreover, lower order organic compounds containing fewer carbons such as methane or methanol were important reusable energy source as alternative energy materials, as well as the raw material of chemical industry. In this study, basic physical and chemical mechanisms of radical reactions of carbon monoxide and hydrogen, generated in plasma-free space or cold plasma by decomposing water vapor and carbon dioxide, were investigated for synthesizing reusable lower order organic compounds such as methane and methanol.
