a Oxidative coupling of FFA with IPA into FBO over different catalysts. Reaction conditions: FFA (0.5 mmol), catalysts (Cu, 3.6 mol%), K2CO3 (0.1 mmol), IPA (5 mL), O2 (2 bar), 120 °C, 16 h. Conversion and yield were determined by GC-MS. For the control catalysts without Cu species, the catalyst usage is 0.03 g. b Control experiments using FFA/FFAL and/or IPA/acetone as substrates over Cu4/Fe0.3Mo0.7O2@C. c Proposed reaction routes and possible by-products. d Oxidative coupling of FFA with secondary and primary alcohols (1a-7a, 8b-15b) into C8~C15 aviation biofuel intermediates over Cu4/Fe0.3Mo0.7O2@C. The error bars represent standard deviation based on three measurements.
