Ceria-titania binary oxide supports of different compositions were obtained via sol-gel and flame spray pyrolysis methods. Sol-gel method allowed better assimilation of ceria and titania precursors, resulting in crystalline mixed oxide supports after calcination. Flame spray pyrolysis produced high surface area oxides with greater amorphous presence. Ceria-titania support crystallinity is identified to be another key aspect towards effective nickel-catalysed low temperature steam reforming of methane.
