Hydrogen production by catalytic decomposition of selected hydrocarbons and H2O dissociation over CeZrO2 and Ni/CeZrO2

Presented paper deals with the catalytic decomposition of hydrocarbons (methane and toluene) in the aspect of H₂ production and types of obtained carbon deposits. The catalyst used in our studies was nickel supported on ceria–zirconia (Ni/CeZrO₂). The aim of this work was to investigate the reactivity of obtained carbon deposits with H₂O. Both issues are of great importance for determining the mechanisms of carbon deposits formation and their suppression during steam reforming reaction.
