Title: Interface Synthesis and Catalytic Property of Microcrystal α-MnO_2
Abstract: A series of MnOx catalysts were prepared by CCl4/H2O interface method using KMnO4,KOH and Mn(NO3)2 solution as precursors.The prepared conditions such as manganese salt,alkali solution,aged time and calcination temperature were changed.Catalytic activities of the catalysts were evaluated in terms of both o-xylene conversion and CO2 yield.XRD,BET and SEM characterizationg results showed the catalyst were prepared at the aged time 24 h and calcination temperature 400 ℃ was microcrystal α-MnO2 nanoparticle.Its specific surface area was 28.962 m2/g.
