Catalytic removal of nitrogen monoxide, carbon monoxide and hydrocarbons

The study is a continuation of our investigations on understanding mechanistic details of three-way catalysts by exploring the L edges of the noble metal components (previous proposal MA-4916 on Pd L edges). Hence, the aim of the present proposal it to conduct operando HERFD-XANES studies at Rh L edges for a Rh/CeO2-ZrO2 three-way catalyst for elucidating: (1) the interaction of CO, C3H6 and NO with the noble metal under reaction conditions, and (2) performing spatially resolved measurements along the catalyst bed at selected temperatures during light-off /light-out.
