Hydrogen from biogas: Catalytic tri-reforming process with Ni/LaCeO mixed oxides

- Ce1−3xLa2xNixO2−δ (x = 0.10; 0.20 and 0.25) as catalysts for tri-reforming process.
- Cubic fluorite structure of CeO2-support retained also at high doping level.
- Interactions nickel-lanthana-surface oxygen vacancies affect catalytic performance.
- LaOx species, increases the d-electron density of nickel atoms.
- Oxidation/coverage of Ni-sites by Lanthana species induces decay of activity.
