Novel NiO/GDC (Gadolinium-doped Ceria) cermet catalysts were developed by the Weak Acid Resin (WAR) method using an ion exchange resin template. In addition, the specific surface area of these tunable materials was enhanced by NiO partial dissolution in aqueous acid solution. The whole procedure highly improved the micro-structural properties of these materials compared to previous studies. Catalysts with high metal loadings (>= 10%), small Ni nanoparticles (<10 nm), and high specific surface areas (>70 m(2)/g) were achieved. These properties are promising for catalytic applications such as methane steam reforming for H-2 production.
