Reactivity of simple alcohols on Fe2O3powders An XPS and FTIR study

摘要: The interaction between α-Fe2O3 powders and methanol, ethanol, propan-1-ol butan-1-ol has been studied by means of FTIR XPS. Mass spectrometry used to characterise the volatile products. Methanol is chemisorbed mainly dissociatively whereas molecular chemisorption prevalent in higher alcohols. When methanol chemisorbed, heating induces formation formate (at temperatures >400 K) while hydrocarbons are main products >500 other Considerations made concerning surface acidic sites connection with thermal treatment sample alcohol chemisorption.
