Preferential oxidation of CO in rich H2 over CuO/CeO2: Details of selectivity and deactivation under the reactant stream

Autor: Guillermo Munuera, D. Gamarra, Ana B. Hungría, Arturo Martínez-Arias

Publikováno v: Applied Catalysis B: Environmental. 65:207-216

A CuO/CeO2 catalyst is examined with respect to its performance for preferential oxidation of CO in H2-rich streams. Catalytic activity results are explained on the basis of characterization by operando-DRIFTS and complemented with the analysis of re
