Considering that packing dielectric materials into the discharge region of a dielectric barrier discharge reactor tends to cause the increase of undesired gas flow resistance and heating effect, herein, we design a combined system (HD-ZnO) of dielectric materials and discharge by integrating a thin ZnO coating into a hybrid discharge (HD) reactor (instead of packing) for effectively synthesizing ozone (O₃) from oxygen (O₂). Using the thin ZnO coating makes O₃ concentration and production yield of HD respectively increased by an average of 28% and 26% with discharge power of 0.4–3.3 W under the optimum conditions, and also avoids the shortcomings of the packing. Discharge diagnosis and physicochemical characterization demonstrate that the enhancement of O₃ synthesis in HD-ZnO relative to HD is mainly ascribed to the strong surface reactions catalyzed by the coating in O₂ plasma. The catalytic performance of ZnO coating on O₃ generation exhibits a good stability during a 4-h uninterrupted test and can be enhanced by reducing the size of ZnO nano-powder and discharge gap of the reactor. Moreover, the designed HD-ZnO possesses a comparable performance with other superior discharge forms on O₃ synthesis.

考虑到将电介质材料填充到介质阻挡放电反应器的放电区域往往会导致不希望的气体流动阻力和加热效应的增加，在此，我们设计了一种电介质材料和放电的组合系统（HD-ZnO），通过集成一个薄的ZnO 涂层进入混合放电 (HD) 反应器（而不是填料），用于从氧气 (O ₂ )有效合成臭氧 (O ₃ )。使用薄ZnO涂层使O ₃浓度和HD的产率分别平均提高28%和26%，在最佳条件下放电功率为0.4-3.3 W，也避免了填料的缺点。放电诊断和理化表征表明，O₃ HD-ZnO 相对于 HD 的合成主要归因于涂层在 O ₂等离子体中催化的强烈表面反应。ZnO 涂层对 O ₃生成的催化性能在 4 小时不间断测试中表现出良好的稳定性，可以通过减小 ZnO 纳米粉体的尺寸和反应器的放电间隙来增强。此外，设计的 HD-ZnO 在 O ₃合成方面具有与其他优异放电形式相当的性能。
