Iron modified MCM-41 materials characterised by methanol oxidation and sulphurisation reactions
SiMCM-41, AlMCM-41, NbMCM-41 were applied as supports for iron species introduced by wetness impregnation and chemical vapour deposition (CVD) methods. Methanol oxidation and sulphurisation were used for the characterisation of catalytic properties. The support nature as well as the type of iron species have no effect on the selectivity of methanol oxidation. However, they bear a significant influence on both the activity and selectivity in the reaction between methanol and hydrogen sulphide. The wetness impregnation of NbMCM-41 and AlMCM-41 with Fe salt leads to the most effective catalysts in the sulphurisation of methanol.
