Preparation of highly effective ferric hydroxide supported noble metal catalysts for CO oxidations: From gold to palladium

---

Abstract.
Ferric hydroxide supported Pd catalyst prepared by a simple co-precipitation method without calcinations
at elevated temperatures and only reduced at 50 ◦C possessed unexpectedly higher activity for CO
oxidations even compared with that of supported Au catalysts. XRD and TEM results showed that the
support was mixture of Fe(OH)x and Fe3O4 and Pd was highly dispersed on it. XPS results showed that
Pd existed as mixture of oxidation and metal state. The large amount of OH group on the supports may
play an important role in O adsorption and activation.
