Abstract
Catalytic steam reforming of bioethanol seems to be a promise option to produce renewable hydrogen; however
efficient catalysts are still under development. Recently, manganese oxide based materials (MO) are the subject of
intense research as low cost, efficient, and environmentally friendly catalysts. Among them MO with layer and tunnel
structure have received significant attention due to their excellent catalytic activity. Specifically, we have explored
the catalytic performance of two MO containing Ni (Birnessite and Todorokite). We find that both materials are
highly active and selective to produce hydrogen by steam reforming of bioethanol. Their characterization by DRX,
BET area, TPR, and TEM, has allowed to find that the excellent performance exhibited by these materials could be
attributed to the especial structure of these MO, which would provide high-quality positions for the stabilization of
the Ni metal particles.
