摘要	In this work, we report a carbon-mediated strategy to construct supported Co-MnOx nano-interfacial catalyst that enables highly selective synthesis of long-chain linear alpha-olefins (C-5+(=)) via the Fischer-Tropsch (FT) reaction. The co-impregnation of glucose as the carbon precursor and metal salt aqueous solution over SiO2 followed by pyrolysis and oxidation creates a catalyst with stable and rich Co-MnOx nano-interfaces after reduction and under FT conditions, which are convincingly revealed from characterizations of the catalysts at different stages. The optimal catalyst is stable for over 400 h without an observably decreased CO conversion, and the highest spacetime yield of C-5+(=) is achieved to be 0.79 g & sdot;gCo(-1)& sdot;h(-1), which are mainly originated from the suppressed sintering of metallic Co and favored CO adsorption/dissociation with a reasonably inhibited H-2 co-adsorption. The simple procedure and broad availability of precursors make our developed strategy a practically important surfaceengineering method capable of precisely fabricating stable nano-interfacial catalysts.
