MnOn/gelatin based carbon beads catalyst for ozone decomposition
Objective To prepare manganese oxides/gelatin based porous carbon beads catalyst,and study its catalytic performance for ozone decomposition.Methods A series of gelatin based porous carbon beads supported MnOn catalysts were prepared by chemical codeposition method(Mn-GBC-4,Mn-GBC-1,Mn-GBC-2,Mn-GBC-3).Characterize its microstructure by XRD,BET,and SEM,and study its moisture resistance and lifespan performance.Results Under normal temperatare and pressure,40％relative humidity and 20 000-1 airspeed,the decomposition rate of ozone reached 97％over Mn-GBC-1,,and the catalyst life showed high stability(～200 h).Conclusion Manganese oxides/gelatin based porous carbon beads catalyst prepared in this study showed excellent ozone decomposition performance and good practical application prospects,and it provided new ideas for developing more efficient ozone decomposition catalysts.
