Abstract

Adding Fe to Pt/SiO2 catalysts improves activity for methanol synthesis from 3H2/CO at 523 K and 3.19 MPa. Over 90% methanol selectivity can be achieved at low conversion, depending on the metal composition and dispersion.In situ Mössbauer measurements after reduction in hydrogen at 673 K and during steady-state reaction show the presence of PtFe alloy and Fe3+ phases only. The amount of PtFe alloy increases as catalysts activate to produce methanol with higher activity and selectivity.
