摘要：NOVELTY - A nitrogen oxide selective catalytic reduction oxygen-rich condition supported silver catalyst comprises silver oxide active component, titania modified alumina carrier, and samarium(III) oxide, potassium carbonate or cobalt(II,III) oxide additive. USE - Nitrogen oxide selective catalytic reduction oxygen-rich condition supported silver catalyst used for diesel exhaust catalytic purification. ADVANTAGE - The catalyst has high catalytic activity and selectivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nitrogen oxide selective catalytic reduction oxygen-rich condition supported silver catalyst comprising taking active component and additive, dissolving in deionized water, adding carrier, soaking at 20-80 degrees C for 1-12 hours, drying, and sintering at 200-800 degrees C.
