Preparation of highly effective ferric hydroxide supported noble metal cataly…

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 r…
