In order to produce an alternative energy of biodiesel using field pennycress (Thlaspi arvense L.) seed oil, a novel Fe₃O₄/graphene oxide-phenylalanine bisulfate ionic liquid core-shell magnetic catalyst was developed. Ferroferric oxide nanoparticles and graphene oxide (GO) were employed to prepare a magnetic carrier of Fe₃O₄@GO nanocomposite which applied to immobilize phenylalanine bisulfate ionic liquid (PBIL). The immobilized PBIL was characterized by the means of characterization. The heterogeneous Fe₃O₄@GO@PBIL catalyst was demonstrated to have a high catalytic efficiency that reached 92.38 % of biodiesel yield under the optimal conditions (methanol/oil molar ratio of 10:1, reaction temperature of 60 °C, reaction time of 4 h, catalyst dosage of 25 wt%, stirring speed of 1500 r/min). After transesterification processes, the catalyst could be easily removed from the reaction mixture with an external magnet and showed little deactivation after multiple recycles. The main properties of biodiesel product were reconcilable with the range of test standards of ASTM D6751 and EN 14214. In summary, the prepared Fe₃O₄@GO@PBIL catalyst behaved a superiorly catalytic performance, which made the produced biodiesel possess the possibility of application to biofuel as an ideal substitution.

为了利用田间豆瓣菜（Thlaspi arvense L.）种子油产生生物柴油的替代能源，开发了新型的Fe ₃ O ₄ /氧化石墨烯-苯丙氨酸硫酸氢盐离子液体核-壳磁性催化剂。用三氧化二铁纳米颗粒和氧化石墨烯（GO）制备Fe ₃ O ₄ @GO纳米复合材料的磁性载体，该载体用于固定苯丙氨酸二硫酸氢盐离子液体（PBIL）。固定化的PBIL通过表征方法表征。异质Fe ₃ O ₄在最佳条件下（甲醇/油摩尔比为10：1，反应温度为60°C，反应时间为4 h，催化剂用量），@ GO @ PBIL催化剂具有很高的催化效率，可达到生物柴油产率的92.38％。 25％（重量），搅拌速度为1500 r / min。进行酯交换反应后，可以很容易地用外部磁体将催化剂从反应混合物中除去，多次循环后几乎没有失活。生物柴油产品的主要性能符合ASTM D6751和EN 14214的测试标准。总之，所制备的Fe ₃ O ₄ @ GO @ PBIL催化剂表现出优异的催化性能，这使得所生产的生物柴油具有应用于生物燃料作为理想的替代品。
