Ozone synthesis from oxygen in narrow?gap hybrid discharge integrated with oxide coating: The role of surface catalytic reactions

To modulate ozone (O3) synthesis, oxide coatings are integrated with a high?efficiency narrow?gap hybrid discharge (HD). It is found that O3 concentration () and energy yield (?) can be enhanced by integrating single?valent oxides in an HD reactor, whereas multivalent oxides show a negative effect on O3 formation. Further studies suggest that surface catalytic reactions occurring on the surface of oxides play a crucial role in determining the performance of O3 synthesis: single?valent oxide coatings with a large specific surface area facilitate O3 production via offering abundant catalytic sites for surface catalytic reactions; surface catalytic reactions on multivalent oxide coatings suppress O3 production because of the dominating O3 decomposition over highly active sites of oxygen vacancies.Integrating oxide coatings with narrow?gap hybrid discharge (HD) can modulate ozone (O3) synthesis. O3 concentration () and energy yield (?) for HD can be enhanced by single?valent oxides, whereas they are reduced by multivalent oxides. The discharge and oxide characterizations suggest that surface catalytic reactions play a crucial role in the synthesis of O3: single?valent oxide coatings facilitate O3 production by offering abundant catalytic sites for surface catalytic reactions; surface catalytic reactions on multivalent oxide coatings suppress O3 production because of the dominating O3 decomposition over highly active sites of oxygen vacancies. This study is inspirational for designing and fabricating high?efficiency O3 generators.
