Methanol steam reforming for hydrogen production over NiTiO₃ nanocatalyst with hierarchical porous structure.

ABSTRACT: Steam reforming for hydrogen production is one of the important research directions for clean energy. NiTiO₃ catalysts with a hierarchical porous structure are prepared and applied to methanol steam reforming for hydrogen production. The results show that the optimum catalyst (10% Ni-Ti-O_x) not only has a hierarchical porous structure, but it also involves the coexistence of NiTiO₃, anatase TiO₂ and rutile TiO₂. The formation of NiTiO₃ is beneficial to the adsorption and activation of methanol molecules on the surface of the Ni-Ti-O_x catalyst, and the main intermediate species of the methanol molecular reaction are hydroxyl groups, methoxy species and formic acid species. Furthermore, the methanol st
