Synthesis of liquid biofuels (C 11 -C 13 ) from cellulosic ethanol is regarded as a promising and versatile protocol. In this study, oxide-supported nanogold catalysts exhibit good catalytic performance in ethanol conversion with cinnamaldehyde and finally give rise to the C 11 -C 13 hydrocarbon. High selectivity (70%) for C 11 -C 13 hydrocarbons is achieved over Au/NiO via a one-pot cascade reaction, viz. cross-aldol condensations in the presence of oxygen and base (K 2 CO 3 ) and then full hydrodeoxygenation with hydrogen gas. EtOH-TPD and TGA analyses show that the ethanol is activated to acetaldehyde (CH 3 CHO*) over the surface oxygen vacancies of the NiO support. The CH 3 CHO* then reacts with cinnamaldehyde at the interfacial perimeter of the Au/NiO composite during the cascade reactions, as evidenced by comparison of the catalytic performance with that over another oxide-supported Au NP, chemo-adsorption investigations, and in situ infrared spectroscopy investigations. This work may provide new guidelines for designing efficient catalysts to convert bioethanol into biofuels with high energy density. a Reaction conditions: 10 mg of 1 wt% Au catalysts, 26 mL of cinnamaldehyde, 10 mg of base, 3 mL of ethanol, 4 h, and 1 MPa air. b The cinnamaldehyde conversion and product selectivity were determined by GC-MS analysis.3656 | Nanoscale Adv., 2019, 1, 3654-3659This journal is
