Abstract:

In this study, Na-ZSM-5 zeolite was used as a support for gold nanoparticles. Two catalysts were prepared in order to compare the effect of iron on the activity of gold catalyst. In Au-Fe/ZSM-5 the support charged in the aqueous solution of Fe(NO3)3,9H2O and calcined in air. Fe loaded zeolite or fresh calcined one was directly charged into the chloroauric acid solution, which was pre-adjusted to pH=6. The solution was prepared by dissolving pure gold in aqua regia. TEM study showed gold nanoparticles were much smaller in iron containing catalyst. CO oxidation results showed that addition of iron improved catalyst activity.
