氧化锰八面体分子筛纳米棒的合成及其催化甲醛低温氧化性能, PP. 97-99 Abstract: ?Uniformmanganeseoxideoctahedralmolecularsieve(OMS-2)nanorodsweresynthesizedbyaddingasmallquantityofK2S2O8tothesolutioncontainingMnSO4·H2OandKMnO4,andusedforcompleteoxidationofformaldehyde.AccordingtotheresultsofN2adsorptionandX-raydiffraction,thematerialisamanganeseoxideoctahedralmolecularsievewiththecryptomelanetypestructure.TEMobservationshowsthatthediametersofthenanorodsrangefrom15to25nm,andthelengthsare300~400nm.CompleteconversionofHCHOtoCO2andH2Ocanbeachievedat353KoverOMS-2,andthesameconversionisobtainedat373KontheMnOxpowderunderthesameconditions,whichdemonstratesthatthecatalyticactivityiscloselyrelatedtothemorphologyofthecatalysts.
