SiO2/TiO2 composites displayed superior performance relative to individual oxides.
TiO2 separating from SiO2/TiO2 composite oxides could inhibit Ni sintering.
The separated TiO2 improved the anti-coking properties of 10Ni/STx catalysts.
The catalysts with a Si/Ti atomic ratio of 5 showed the best catalytic performance.
