Effect of precursor synthesis on catalytic activity of Co3O4 in N2O decomposition

Original language description

Series of precursors was prepared by precipitation of cobalt nitrate in aqueous solutions using vari-ous precipitation agents (NH3.H2O, NaOH, Na2CO3) and reactions conditions (OH/Co molar ratio, agingtime). Powder XRD showed different phase composition of the obtained precursors, in which -Co(OH)2,CoII-CoIIIlayered double hydroxide, and basic cobalt carbonate were identified. Only Co3O4spinel-likeoxide was found in products after heating at 500°C in air but different N2O conversions were observedover the examined oxide catalysts. Especially the catalysts obtained from -Co(OH)2precursors showedhigh catalytic activity in N2O decomposition. The correlation between methods of preparation, phasecomposition of precursors, catalytic properties of the relatedoxide catalysts, and the role of the cobaltions as catalytic active sites is discussed.
