Key Points

The aim is to understand how by-products are formed during the catalytic reduction of NO using hydrogen.
Examined reduction of NO over alumina-supported Pt, Pd, and Rh catalysts
Analyzed the formation of N2O as a by-product
Investigated reaction mechanisms during catalytic processes
Identified formation of N2O as a significant by-product during NO reduction
Demonstrated differences in catalyst efficiency and by-product formation among Pt, Pd, and Rh
Revealed insights into optimizing conditions to minimize unwanted by-products

Implication

Elucidates the formation of by-products during NO purification with hydrogen on various catalysts, indicating implications for cleaner emissions.

Abstract

We elucidate the formation mechanism of by-products especially N 2 O during NO purification using H 2 as a reductant on alumina-supported Pt, Pd, and Rh catalysts by looking into the catalytic reaction.
