Ruthenium based catalysts for catalytic oxidation of NO with different supports

We propose to study the active state of 5wt% Ru loaded catalyst on different catalyst supports at typical NO oxidation conditions for industrial-scale nitric acid synthesis. Hardly any literature reports exist on catalytic oxidation of NO at high concentration, but Ru on zirconia, ceria, titania, and alumina proves to be a satisfactory catalyst for NO oxidation with water, NO2 and a higher NO concentration in our in-house research. We, therefore, want to perform an in-situ investigation on different catalyst supports with 5wt% Ru loaded to it in the presence & absence of NO2. XAS-XRD in combination with mass spectrometry is an excellent combination for studying the local Ru environment in these catalysts at industrially relevant conditions.
