Abstract:
Pt/ZnO catalysts prepared with different supports, ZnO powders and ZnO nanowires, after reduced at different temperatures were tested in water gas shift reaction. The Pt/ZnO powders catalysts with irregular spherical ZnO morphology exhibited a higher activity than Pt/ZnO nanowires catalysts after same reduction treatment. Both catalysts had the highest activity after reduced at 300°C, a further increase in reduction temperatures led to a decrease in catalytic activity. Different techniques (XRD, XPS, SEM and TEM) were used to characterize both types of catalysts after each reductive treatment in order to correlate the microstructure to the catalytic behavior. Influence of the observed structural features such as alloy formation, particle size difference, Cl concentration and property of support are discussed.
