通过在低气压范围内使用射频脉冲放电而无需催化，研究了二氧化碳还原为可重复使用的有机材料（包括甲烷和甲醇）的基本现象。放电在不同的放电参数（例如电压、气体流量、气体混合比和气体停留时间）下进行，其中二氧化碳与氢气在总气压为 1–10 Torr 的情况下混合。观察到有机物质，例如甲烷和甲醇。一氧化碳是二氧化碳的主要产物。甲烷是排放产生的主要有机物质。甲烷的浓度随着放电电压的增加而增加，其体积分数达到来自二氧化碳的含碳产物的10%~20%。该分数还取决于二氧化碳和氢气的混合比。我们还观察到甲醇的形成，尽管与甲烷相比，其含量较低，只有几个%。
Basic phenomena of the reduction of carbon dioxide to reusable organic materials including methane and methanol were investigated by using a radio frequency impulse discharge in a low gas pressure range without catalysis. The discharge took place under different discharge parameters such as voltage, gas flow rate, gas-mixing ratio, and gas residence time, where the carbon dioxide was mixed with hydrogen at total gas pressure of 1–10 Torr. Organic materials such as methane and methanol were observed. Carbon monoxide was a major product from carbon dioxide. Methane was the dominant organic species produced by the discharge. The concentration of methane increased with discharge voltage, and its volume fraction attained 10–20% of the products containing carbon that came from carbon dioxide. This fraction was also dependent on the mixing ratio of carbon dioxide and hydrogen. We also observed the formation of methanol, though its fraction was low, a few %, compared with methane.
