Co-Mn mixed oxide catalysts prepared by hydrothermal deposition on stainless steel wire meshesF. Kovanda, M. Dvořáková, Department of Solid State Chemistry, University of Chemistry and Technology, Prague, Czech Republic and K. Jirátová, J. Balabánová, P. Topka, Institute of Chemical Process Fundamentals of the CAS, Prague, Czech RepublicThe present work was focused on preparation of supported Co-Mn mixed oxide catalysts as both Co and Mn oxides show high catalytic activity in various oxidation reactions and catalysts supported on metal meshes can be applied in any kind of reactor especially that designated for fast reactions. Thin layer of active oxidesenables their high utilization due to low internal diffusion effects. The stainless steel meshes used as support were treated under hydrothermal conditions in Co and Mn nitrates aqueous solutions containing urea and then heated at 500 °C in air to obtain supported Co-Mn mixed oxides with various Co:Mn molar ratios. The other set of non-supported catalysts was prepared by coprecipitation of Co and Mn nitrates and subsequent heating at 500 °C in air. The XRD, SEM, TPR, and XPS were used for the catalysts characterization and their activity was examined in deep oxidation of ethanol.
