The selective and stable conversion of ethene to propene, 3C(2)H(4) -> 2C(3)H(6), was found on Ni-loaded mesoporous silica catalysts in a continuous gas-flow system at around 673 K and atmospheric pressure. The one-path conversion of ethene was 68%, and the propene selectivity was 48%. Nickel ion alone showed the specific activity for the reaction among 13 kinds of metal ions examined. The reaction mechanism was discussed from the viewpoints of metathesis and decomposition.
