Highly dispersed Ni catalysts on spherical SiO 2 were prepared by simple impregnation of Ni(acac) 2 , [Ni‐(NH 3 ) 6− n (H 2 O) n ] 2+ , [Ni(en) 3 ] 2+ and [Ni(EDTA)] 2− . Pulse adsorption of H 2 and TEM analysis results confirmed that Ni was dispersed very well on the surface of SiO 2 even after calcination (4 h) and reduction (1 h) at high temperature of 800 °C. These highly dispersed and uniquely sized Ni crystallites were more stable and more reactive for both autothermal reforming and partial oxidation of methane in fluidized reactor.
