Pd in the La- based perovskite partially displays a reversible diffusion mechanism under redox atmospheres at 600° C. These effects produce a self-regenerative mechanism at relatively high temperatures. Catalytic testing under model gas mixtures of powders and coatings of these perovskites proves the potential of these materials for effective NOx-reduction under lean conditions. Hydrogen provides the best NO- reduction results among the employed reducing agents (i.e. H2, C3H6, and C8H18). The Pd-integrated Perovskites display peak NO-conversions of 72 % and N2-selectivities of 72 % in the presence of H2O- vapour and CO2 at temperatures below 300°C. For instance, Ba- and Ce- substituted perovskites are also active for NO-reduction up to 400°C.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838111827\"\u003e\u003ch3\u003eDevelopment and characterization of NOx-reductive catalytic coating systems for lean-burn engines\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783838111827","offer_id":39442581291101,"sku":"9783838111827","price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/240bee0c-f9da-4654-aec6-908e17c1cc2c.jpg?v=1778051808","url":"https:\/\/shop.autorenwelt.de\/products\/nox-reductive-perovskite-catalysts-for-lean-burn-engines-development-and-characterization-of-nox-reductive-catalytic-coating-systems-for-lean-burn-engines-von-guillermo-cesar-mondragon-rodriguez","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
