AbstractOMS-2-based catalysts hold the promise of practical applications in ozone decomposition for their excellent activity, yet improvement of water resistance property remains challenging. Here, we reported an innovative Li-K-OMS-2 catalyst which possessed specific non-oxygen vacancy sites for H2O adsorption in the tunnel framework. This catalyst showed the decrease of only similar to 10 % of ozone conversion after reaction for 6 h under the RH of 90 %, the initial ozone concentration of 45 ppm and GHSV of 660,000h(-1) at 25 degrees C, which was superior to the currently documented MnO2-based catalysts. Both physiochemical characterization and DFT calculations revealed that the excellent water resistance property of Li-K-OMS-2 could be attributed to the formation of designed novel non-oxygen vacancy sites for H2O adsorption, which effectively alleviated the catalyst deactivation caused by non-dissociative adsorption of H2O on oxygen vacancies. The findings represented a critical step towards the rational design and synthesis of high water-resistant catalyst for ozone decomposition.
