Efficient ozone decomposition over bifunctional Co3Mn-layered double hydroxide with strong electronic interaction
文献摘要：
Ground-level ozone is one of the primary pollutants detrimental to human health and ecosystems.Cat-alytic ozone decomposition still suffers from low efficiency and unsatisfactory stability.In this work,we report a manganese-based layered double hydroxide catalyst(Co3Mn-LDH),which exhibited a superior ozone decomposition performance with the efficiency of 100％and stability over 7 h under a GHSV of 2,000,000 mL g-1h-1 and relative humidity of 15％.Even when the relative humidity increased to 50％,the ozone decomposition also reached 86％,which significantly exceeds as-synthesized MnO2 and com-mercial MnO2 in performance.The catalytic mechanism was studied by H2-TPR,FT-IR and XPS.The excel-lent performance of Co3Mn-LDH can be attributed to its abundant surface hydroxyl groups that ensured the preferentially surface enrichment of ozone,as well as the cyclic dynamic replenishment of electrons between multivalent Co2+/Co3+,Mn2+/Mn3+/Mn4+and oxygen species that endowed the stable ozone decomposition.This work offers new insights into the design of efficient catalysts for ozone pollution control.
