The insights of global carbon neutralization/recycling accentuate liquid fuel (LF) through Fischer-Tropsch Synthesis (FTS) from CO/H₂ derived from renewable energy mediated potential CO₂ conversion with H₂O, but the catalyst issue makes it challenging. This presentation disclosed regulation of LF productivity by different combinations of supporting materials (SM) with hybridizing materials (HM) in Co-based catalysts and a rational 0.7Al₂O₃/2.0ZSM5 (A) afforded ~63 % LF yield, contrast to usual ~35 % from CO/H₂. Relative to other with different SM/different HM, Co-A regulated potentially dispersed FTS secured Co nanoparticle surface (CNS) properties and revealed a tandem process of CH₂-polymerization and hydrocracking/hydro-isomerization, suppressing methanation/Water-gas-shift reaction.
