Marked Effect of Mo and Fe Addition Upon Liquid Phase Methanol Reforming with Water Over Al2O3 Supported Pt Catalysts
Successively impregnated Pt-Mo/Al2O3 and Pt-Fe/Al2O3 catalysts exhibited large enhancement effect in H-2 formation rate of liquid phase methanol reforming. Added Mo oxide forms monolayer on Al2O3 and facilitates the higher dispersion of Pt particles. In the case of Fe, formation of some surface bimetallic clusters between Pt and Fe was confirmed by XAS analysis, which causes the enhancement effect of H-2 formation in MeOH-H2O reaction.
