PEROVSKITE-BASED CATALYST WITH IMPROVED SULFUR RESISTANCE

摘要

PURPOSE:, which being provided to the time for shortening rich-spike with improved perovskite-based catalyst sulfur resistance, and reduces waste of fuel generates hydrogen by decomposing to generate the material of hydrogen and supply glibly based on exhaust gas component. ;CONSTITUTION: the catalyst of perovskite-based catalyst carrier includes one or more support perovskite particles, oxygen absorption and releasable material, composite oxide carrier and hydrogen-generating material. Oxygen absorbs and releases material by cerium oxide, silica, oxysulfide or mixture identical or concrete composition Ti/ZrO_2, Hf/ZrO_2, mixture it is identical. Hydrogen-generating material by Rh/ZrO_2 particles, Pt/CeO_2 particles or mixture it is identical. It includes aluminium oxide, ceria, titanium dioxide, magnesia, silica and zirconium oxide that the mixture of one or more of the catalyst carrier, which is selected from,. ;The 2012 of copyright KIPO submissions
