Aseries of Y₂O₃-modified Ni/SiO₂ catalysts were synthesized by a conventional impregnation method. Catalytic performances for the partial oxidation of methane (POM) to synthesis gas were investigated. The addition of Y₂O₃ promotes a decrease in size of Ni particles supported on silica, increased the dispersion of Ni particles, and enhanced the interaction between Ni and silica. These properties gave the catalysts increased anti-sintering and resistance to carbon deposits. The catalytic behaviors of the Ni-based catalysts for POM were significantly improved when Y₂O₃ was introduced.
