Decomposion of indoor ozone on activated carbon-supported catalysts

摘要：

Activated carbon-supported copper, silver and manganese catalysts (Cu/GAC, Ag/GAC and Mn/GAC) were prepared by impregnation. Orthogonal experiments were conducted to find the optimum preparation conditions including metal loading, calcination temperature and calcination time. Each catalyst was prepared under the optimum conditions. Catalytic activities for decomposition of ozone of Cu/GAC, Ag/GAC, Mn/GAC, activated carbon (GAC) and molecular sieve (MS) were investigated. The comparison experiments showed that Ag/GAC had the highest activity and was an ideal catalyst to remove indoor ozone. X-ray Diffraction (XRD) of Cu/GAC, Mn/GAC and Ag/GAC showed that copper and silver were loaded as atoms on activated carbon, while manganese was present as the monoxide. Finally, possible mechanisms for ozone decomposition on the surface of Cu/GAC, Ag/GAC and Mn/GAC are proposed.
