The conversion and utilization of CO 2 is one of the greatest global challenges. Plasma assisted catalysis provide a new resolution to this problem. However, the energy efficiency and conversion rates of the plasma process are still insufficient for industrial applications. The key reasons are the highly complex interaction between gaseous plasma and catalytic materials, especially in packed bed dielectric barrier discharges. Our study fills this critical gap by developing a novel numerical approach to study how the ns pulse driving plasma trigger the heterogeneous reactions on the Ni/ γ -Al 2 O 3 catalyst surface. The development of plasma inside the reactor is in the form of surface ionization wave (SIW) + filamentary microdischarges. The high electron power in the SIW region and the high ion power density in the sheath region on the catalysts surface provide enough energy to trigger heterogenous reactions. The heterogeneous reactions not on...

填充床介质阻挡放电反应器中的等离子体增强了表面反应

CO 2的转化和利用是全球最大的挑战之一。等离子体辅助催化为该问题提供了新的解决方案。然而，等离子工艺的能量效率和转化率对于工业应用而言仍然不足。关键原因是气态等离子体与催化材料之间的相互作用非常复杂，尤其是在填充床介质阻挡放电中。我们的研究通过开发新颖的数值方法来研究ns脉冲驱动等离子体如何触发Ni /γ-Al 2 O 3催化剂表面上的异相反应，从而填补了这一关键空白。反应器内部的等离子体以表面电离波（SIW）+丝状微放电的形式出现。SIW区中的高电子功率和催化剂表面上鞘区中的高离子功率密度提供了足够的能量来触发异质反应。异构反应不在...
