摘要: Abstract Manganese oxide catalysts supported on monolithic yttria stabilized zirconia honeycombs were studied for H 2 O decomposition in view of space propulsion applications. The materials prepared by impregnation (IM), precipitation (PR) and sol–gel (SG) methods characterized N adsorption, SEM temperature programmed reduction (TPR). catalytic activity was under vapour phase conditions. tests carried out a flow apparatus at T = 200 °C, gas hourly velocity (GHSV) = 2.00 2.67 s −1 , concentrations 11.3 mol%. redox properties the markedly influenced preparation method. In SG catalyst, large fraction Mn not reducible TPR differently from PR IM materials. Despite this effect, catalyst showed an comparable or higher than that IM, due to more effective dispersion species. A too strong effect conversion attributed autocatalytic effect. radical mechanism hypothesized: it assumed reaction between species produced radicals promoted overall reaction.
