Title: Preparation of Manganese Oxide Catalysts Using Novel NH4MnO4 and Manganese Hydroxide Precursors. Comparison of Unsupported and Alumina Supported Catalysts
Abstract: Summary Unsupported and alumina supported manganese oxide catalysts were prepared using manganese nitrate, manganese hydroxide and ammonium permanganate. They were bulk and surface characterized by thermal analysis, X-ray diffraction, diffuse reflectans, IR and photoelectron spectroscopy, S BET and TPR. Moreover H 2 O 2 decomposition and CO oxidation were used as test reactions. The most active supported catalysts are the manganese hydroxide coated samples which show a Γ-Mn 2 O 3 phase. For the ammonium permanganate-based catalysts a strong interaction with the carrier was evidenced.
