CO hydrogenation over TiO2-supported ultrafine Fe3O4 particle catalysts prepared by a colloid chemical method

The properties of TiO2 supports and the H2 reduction temperature of Fe3O4/TiO2 catalysts were found to play imortant roles in determining their activity and light olefin selectivity. For each catalyst, a good linear relationship was observed between the CO conversion and the light olefin selectivity. The sequence of the latter under identical conditions was JRC-TIO-5>TIO-3>TIO-4.
