Re-investigation of the thermal decomposition of Co(CO)(4)SiCl3 adsorbed on silica

Evidence is provided that thermal decomposition of Co(CO)(4)SiCl3 adsorbed on silica in a hydrogen atmosphere results in the formation of metallic cobalt nanoparticles covered with a Co2SiO4/CoO shell instead of cobalt silicide nanoparticles, as had been reported previously.
