Plasma has been studied for several years to convert CO 2 into value-added products. If CO 2 could be converted in the presence of H 2 O as a cheap H-source for making syngas and oxygenates, it would mimic natural photosynthesis. However, CO 2 /H 2 O plasmas have not yet been extensively studied, not by experiments, and certainly not computationally. Therefore, we present here a kinetic modelling study to obtain a greater understanding of the vibrational kinetics of a CO 2 /H 2 O microwave plasma. For this purpose, we first created an electron impact cross section set for H 2 O, using a swarm-derived method. We added the new cross section set and CO 2 /H 2 O-related chemistry to a pure CO 2 model. While it was expected that H 2 O addition mainly causes quenching of the CO 2 asymmetric mode vibrational levels due to the additional CO 2 /H 2 O ...

H 2 O对CO 2 / H 2 O微波等离子体中CO 2振动种群的影响：动力学模型研究

已经对等离子体进行了数年的研究，以将CO 2转化为增值产品。如果CO 2可以在H 2 O的存在下转化为廉价的H源，用于制造合成气和含氧化合物，它将模拟自然光合作用。但是，尚未对CO 2 / H 2 O等离子体进行广泛的研究，没有通过实验，当然也没有进行计算。因此，我们在这里进行动力学建模研究，以更好地了解CO 2 / H 2 O微波等离子体的振动动力学。为此，我们首先使用群体算法为H 2 O创建了一个电子冲击截面集。我们将新的截面集和与CO 2 / H 2 O相关的化学反应添加到了纯CO 2模型中。预计由于添加了额外的CO 2 / H 2 O ...，H 2 O的添加主要会导致CO 2不对称模式振动能级的猝灭。
