It is still not clear at the molecular level how the acidic silanol and basic alkylamine bifunctional groups over SBA-15 zeolite exert catalytic functions in aldol condensation of 5-hydroxymethylfurfural (HMF) with acetone, which plays pivotal roles in the synthesis of renewable fuels from biomass. Here, the catalytic mechanisms of the aldol condensation (1) of 5-hydroxymethylfurfural (HMF) with acetone to produce 4-[5-(hydroxymethyl)-2-furanyl]-3-buten-2-one (C9H10O3) over acidic [−SiOH], basic [−RNH2], and cooperative acidic–basic [−SiOH/–RNH2] active sites on the alkylamine-grafted SBA-15 zeolite (SBA-15–RNH2) have been theoretically investigated, combining quantum mechanical and molecular mechanical calculations, which involves aldol condensation (2) and dehydration (3). Based on the plausible reaction pathways, the revised mechanism is proposed. Toward the aldol condensation (2), the cooperative [−SiOH/–RNH2] displays better catalytic activity than the single [−RNH2] or [−SiOH], in which the rate-det...
