Ce0.75Si0.25O2 or Ce0.65Mn0.1Si0.25O2 were used as supports for Co FT synthesis.
- •
Cobalt carbide was formed under the FT synthesis conditions selected.
- •
Cobalt carbide formation enhances oxygenates selectivity.
- •
The support plays an important role in controlling FT product selectivity of Co.
