Ni catalysts supported on SiO2 are prepared via a facile combustion method. Both glycine\nfuel and ammonium nitrate combustion improver facilitate the formation of much smaller Ni\nnanoparticles, which give excellent activity and stability, as well as a syngas with a molar ratio\nof H2/CO of about 1:1 due to the minimal side reaction toward revserse water gas shift (RWGS) in\nCH4 dry reforming.
