WebDec 3, 2024 · It is found that the Fe5C2 (510) surface may be covered with a layer of H in FTO process. The mechanism of Fischer-Tropsch synthesis on the Fe5C2 (510) surface prefers to proceed via the CO... WebA quantitative approach is used to understand the chain growth mechanism in FT synthesis on the Ru, Fe, Rh, and Re surfaces. The C−C coupling reactions are extensively calculated on the stepped metal surfaces. Combining the coupling barriers and reactant stabilities, we investigate the reaction rates of all possible C1 + C1 coupling pathways on the metal …
