Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC07469F, CommunicationYuefeng Liu, Ileana Florea, Ovidiu Ersen, Cuong Pham-Huu, Christian Meny
The introduction of a thin layer of TiO2 on [small beta]-SiC allows a significant improvement of the cobalt dispersion. This catalyst exhibits an excellent and stable catalytic activity for the Fischer-Tropsch synthesis (FTS) with high C5+ selectivity, which contributes to the development of a new active catalyst family in the gas-to-liquid process.
