摘要
建立了基于分子反应动力学的氧等离子体化学反应模型,该模型包括了电子与氧分子,以及氧原子与氧分子的碰撞反应过程。利用反应动力学理论计算并讨论了电激励O2(1△)发生器的放电参数,发现电子能量应小于2.5eV。电子浓度对O2(1△)产率的影响不大,当放电压力与气体线流速一定时,存在最佳的电子平均能量。
The model of plasma chemistry was developed to predict the appropriate electron mean energy and flow rate and discharge pressure for the generation of singlet oxygen molecule, based on physical chemistry with a simple reaction model. The model included the collisions of atom with molecule and electron with other species. It is found that the electron mean energy must be less than 2.5 eV. An optimum electron mean energy can be found at constant discharge pressure and flow rate. Electron density and discharge pressure play the second role among the parameters.
