A macro-meso-porous monolithic Ni-based catalyst was prepared via an impregnation route using polystyrene foam as the template and then used in the steam reforming of ethanol to produce a H2-rich gas. The Ni/Mg-Al catalyst has a hierarchically macro-meso-porous structure as indicated by photographs and scanning electron microscopy (SEM). The surface area of the catalyst was 230 m2?g-1 and the Ni dispersion was 5.62%. Compared to the pelletized sample that was prepared without a template, the macro-meso-porous Ni/Mg-Al monolith exhibited superior reactivity in terms of H2 production and also had lower CH4 yields at 700oC and 800oC. Furthermore, the monolithic catalyst maintained excellent activity and H2 selectivity after 100-h on-stream at 700oC, as well as good resistance to coking and metal sintering.
