Abstract

2,5-Dimethyltetrahydrofuran (DMTHF) is deoxygenated to <i>n</i>-hexane with >99% selectivity at mild conditions (90 °C, 1 bar H<sub>2</sub> pressure, fixed-bed reactor) in the presence of the bifunctional metal-acid catalyst Pt-CsPW comprising Pt and Cs<sub>2.5</sub>H<sub>0.5</sub>PW<sub>12</sub>O<sub>40</sub> (CsPW), an acidic Cs salt of Keggin-type heteropoly acid H<sub>3</sub>PW<sub>12</sub>O<sub>40</sub>. Addition of gold to the Pt-CsPW catalyst increases the turnover rate at Pt sites more than twofold, whereas the Au alone without Pt is not active. The enhancement of catalyst activity is attributed to PtAu alloying, which is supported by STEM-EDX and XRD analysis.
