The impact of phase changes, alloying and segregation in supported RhPd catalysts during selective NO reduction by H2
The impact of phase changes, alloying and segregation in supported RhPd catalysts during selective NO reduction by H2
Illuminating complexity: Time resolved, microreactor-based, EDE/mass spectrometry (EDE = energy dispersive extended X-ray absorption fine structure) was used to probe the behaviour of both Rh and Pd components of alloyed nanoparticles during NO reduction by H2. The surface enrichment in Pd is shown to curtail the rapid oxidation of the Rh component by NO and leads to a promotion of NO reduction.

Abstract
Illuminating complexity: Time resolved, microreactor-based, EDE/mass spectrometry (EDE = energy dispersive extended X-ray absorption fine structure) was used to probe the behaviour of both Rh and Pd components of alloyed nanoparticles during NO reduction by H2. The surface enrichment in Pd is shown to curtail the rapid oxidation of the Rh component by NO and leads to a promotion of NO reduction.
