[ДСТУ] Catalytic Activity in CO Oxidation of MnOx Supported on Oxide and Zeolite Carriers / L. V. Lutsenko et al. French-Ukrainian Journal of Chemistry. 2015. Vol. 3, no. 2. P. 54—64. DOI: 10.17721/fujcV3I2P54-64 (date of access: 25.07.2026).
Catalytic activity in CO oxidation was investigated for MnOx-containing materials, prepared by impregnation of SiO2, Al2O3 and zeolites (ZSM-5, ERI). The catalysts were characterized by temperature-programmed reduction (TPR) by hydrogen, diffuse-reflectance UV–Vis (DR UV–Vis) and infra-red (IR) spectroscopy of adsorbed CO. Effect of the previous treatment of the MnOx-containing systems on the catalytic performance has been established. Higher catalytic activity in CO oxidation of the materials treated with air as compared with treated with hydrogen can be explained by presences of manganese ions in +3 and +4 oxidation states. 3%Mn-SiO2 previously treated with air at 350 °C is found to be the most active catalyst among the studied ones.
