The so called ‘burst mode’, a rapidly pulsed power regime for dielectric barrier discharges (DBDs) has previously been reported to greatly improve the performance of an uncooled and unpacked DBD reactor for CO₂ splitting. Here we explore the interaction between a DBD in burst mode and each of active cooling and a dielectric packing material (1.0–1.2 mm glass beads) in a coaxial, metal-dielectric DBD reactor for CO₂ splitting. The effect of burst mode on CO₂ conversion and energy efficiency under different combinations of cooling and packing were investigated and compared with those under continuous wave mode operation. The burst mode operation showed similar CO2 conversion and energy efficiency to continuous wave mode in the unpacked and uncooled configuration under the conditions investigated in this study. However, burst mode significantly outperformed continuous wave mode in the packed and uncooled configuration. When active cooling was employed, burst mode was found to provide only minor benefit or no benefit, depending on specific energy input (SEI), compared to continuous wave mode for each the packed and unpacked configurations. Maximum conversion and energy efficiency were achieved with both packing and active cooling across all SEI examined, and performance in this configuration was found to be relatively insensitive to the power delivery mode.

之前曾报道过所谓的“突发模式”，即一种用于介质阻挡放电 (DBD) 的快速脉冲功率状态，可以极大地提高未冷却和未包装的 DBD 反应器的 CO ₂裂解性能。在这里，我们探讨了突发模式下的 DBD 与用于 CO ₂分裂的同轴金属介电 DBD 反应器中的每一种主动冷却和介电填充材料（1.0-1.2 毫米玻璃珠）之间的相互作用。突发模式对 CO _{2 的影响}研究了不同冷却和填料组合下的转化率和能量效率，并与连续波模式操作下的进行了比较。在本研究调查的条件下，突发模式操作在未包装和未冷却的配置中显示出与连续波模式相似的 CO2 转换和能源效率。然而，在填充和非冷却配置中，突发模式明显优于连续波模式。当采用主动冷却时，与连续波模式相比，对于每种填充和未填充配置，突发模式仅提供很小的好处或没有好处，具体取决于特定的能量输入 (SEI)。在所有 SEI 检查中，通过填料和主动冷却实现了最大的转换和能源效率，
