4. 3. Microstructural Changes in Deactivated Noble Metal Catalysts

   Författare :Bertil Stenbom; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The structural deactivation of supported noble metal catalysts has been investigated for treatments at different temperatures and in different atmospheres. The sintering rates of Pt/Al2O3, Rh/Al2O3, and Pt-Rh/Al2O3 catalysts were measured using temperature-programmed desorption of CO (CO-TPD) and transmission electron microscopy (TEM). LÄS MER
