摘要：The selective hydrogenation of natural oils to produce fatty alcohols is a key process for synthesizing liquid alkanes and high-value chemicals. However, the development of catalysts capable of enhancing hydrodeoxygenation (HDO) selectivity while suppressing carbon-carbon (C-C) bond cleavage to minimize carbon loss remains a significant challenge. In this study, a FeReO x /CeO2 catalyst was developed, which was characterized by high selectivity to octadecanol (93.8%, 210 degrees C) and liquid alkanes from stearic acid under mild conditions. Notably, the FeReO x /CeO2 catalyst exhibited a higher hydrodeoxygenation selectivity in the production of liquid alkanes than decarboxylation (DCO) (C18: 84.2% vs C17: 15.8% at 240 degrees C). Detailed characterization of the FeReO x /CeO2 catalyst revealed that excellent catalytic activity originated from the synergistic interaction between Fe and ReO x . The introduction of ReO x not only enhanced the adsorption of stearic acid but also improved the dispersion of metallic Fe. The weak acidity of metallic Fe could inhibit the cleavage of the C-C bond to a certain extent to obtain alkane products with high hydrodeoxygenation selectivity. Furthermore, the catalyst exhibited strong stability without significant deactivation after five cycles.
