Effect of Pt and Ru promoters on deactivation of Co catalysts by C deposition during Fischer-Tropsch synthesis: A DFT study

- The effect of Pt and Ru promoters on C deposition on Co catalyst is explored using DFT.
- Pt and Ru promoters inhibit C formation by increasing the barrier for C bond formation.
- The stability of C compounds is reduced in the presence of these promoters.
- Pt and Ru promoters influence various pathways of C formation reducing C deposition.
