OP-II-3

PP-II-4The control of the catalytic bed and the different preparation key parameters ofthe catalysts remain an important way to improve the catalytic decomposition and thecatalytic ignition performances: (i) honeycomb-type ceramic monoliths, (ii) washcoatingprocedure, (iii) impregnation steps: the active phase is deposited inside theporosity of the coating layer by impregnation of the active phase precursor followedby drying, calcination and/or reduction. The monolithic catalysts based on the noblemetals are characterized by different physico-chemical techniques to understandtheir behavior.References[1]. R.W. Humble, G.N. Henry, W.J.
