In this context, supported nickel nanoparticles with sizes of 1.3 ± 0.2 and 2.1 ± 0.2 nm were synthesized on silica and ceria, respectively, via a two-step colloidal approach. First, 2-nm nickel–silicide colloids were synthesized from Ni­(COD)2 and octylsilane at low temperature; they were subsequently dispersed onto supports prior to reduction under H2. The resulting catalysts display high activity in dry reforming compared to their analogues prepared using conventional approaches, ceria providing greatly improved catalyst stability. ER -
