DFT and kinetic evidences of the preferential CO oxidation pattern of manganese dioxide catalysts in hydrogen stream (PROX)

Autor: Francesco Arena, Dario Duca, Gianmario Martra, L. Frusteri, Francesco Ferrante, Roberto Di Chio, Giuseppe Bonura, Francesco Frusteri, Sara Morandi, Antonio Prestianni

The oxidation functionality of Mn(IV) sites has been assessed by density functional theory (DFT) analysis of adsorption and activation energies of CO, H2 and O2 on a model Mn4O8 cluster. DFT calculations indicate that Mn(IV) atoms prompt an easy CO c
