2. 1. Preparation and characterisation of perovskite and noble metal promoted oxide based catalysts

   Author : Leif Dahl; Ragnar Larsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; oorganisk kemi; Inorganic Chemistry;

   Abstract : This work concerns efforts to improve or replace noble-metal based catalysts used for car exhaust purification.Various oxide based catalysts have been prepared by impregnating washcoats such as (-Al2O3 and SiO2 with appropriate metal ions, and assemblies calcinated at elevated temperatures have been tested for catalytic activity in the oxidation of CO and C3H6 and reduction of NO.
