Efficient solution combustion synthesis of ceria-based catalysts for hydrogen production

Résumé

This work deals with the development of effective ceria-based materials for the catalytic production of hydrogen from CH4/H2O mixture. For this, pure ceria and ceria doped with noble metals (Ir, Rh) were prepared by a non-conventional one-pot method, namely solution combustion syntheses (SCS). The studied powders were physically characterized and tested in steam reforming of methane (SRM) at 750°C, under highly water-deficient conditions (CH4/H2O molar ratio of 10) with/without H2S. The as-prepared catalysts appear highly active in SRM and resistant to poisoning by carbon and sulfur. The performances could be further improved by a mild thermo-chemical treatment, which was optimized and correlated with the structure of the active surface sites and their reactivity toward CH4. The investigation of the catalytic properties confirms that, with the SCS method, catalysts with stable and reproducible performances can be prepared in a simple manner.
