  "description" : "Heterogeneous CaFe{sub 2}O{sub 4}–Ca{sub 2}Fe{sub 2}O{sub 5}-based catalyst with weak magnetism was prepared by co-precipitation and calcination. It was characterized by various techniques including X-ray diffraction, X-ray photoelectron spectroscopy and temperature programmed desorption method. Its active components were identified as mainly Ca–Fe composite oxides such as CaFe{sub 2}O{sub 4} for transesterification. The magnetism was further strengthened by reducing its component of Fe{sub 2}O{sub 3} to Fe{sub 3}O{sub 4}–Fe under H{sub 2} atmosphere for better magnetic separation. Both catalysts were used for the catalytic transesterification of soybean and Jatropha oils to biodiesel. The highest biodiesel yields for soybean oil of 85.4% and 83.5% were obtained over the weak and strong magnetic catalysts, respectively under the optimized conditions (373 K, 30 min, 15/1 methanol/oil molar ratio and 4 wt% catalyst). The catalysts could be recycled three times. Biodiesel production from pretreated Jatropha oil was tested with the magnetic CaFe{sub 2}O{sub 4}–Ca{sub 2}Fe{sub 2}O{sub 5}–Fe{sub 3}O{sub 4}–Fe catalyst, and 78.2% biodiesel yield was obtained. The magnetic CaFe{sub 2}O{sub 4}–Ca{sub 2}Fe{sub 2}O{sub 5}-based catalyst shows a potential application for the green production of biodiesel. - Highlights: • Magnetic catalyst was prepared by co-precipitation, calcination and reduction. • The catalyst was composed of CaFe{sub 2}O{sub 4}–Ca{sub 2}Fe{sub 2}O{sub 5}–Fe{sub 3}O{sub 4}–Fe. • Biodiesel yields of 83.5% and 78.2% were achieved for soybean and Jatropha oils. • The catalyst was easily separated by a magnet and used for three cycles.",
