Core-shell Fe3O4@silica magnetic nanoparticles functionalized with a strong base, triazabicyclodecene (TBD), were successfully synthesized for harvesting microalgae and for one-pot microalgae-to-fatty acid methyl ester (FAME, or so-called biodiesel) conversion. Three types of algae oil sources (i.e., dried algae, algae oil, and algae concentrate) were used and the reaction conditions were optimized to achieve the maximum biodiesel yield. The results obtained in this study show that our TBD-functionalized Fe3O4@silica nanoparticles could effectively convert algae oil to biodiesel with a maximum yield of 97.1 %. Additionally, TBD-Fe3O4@silica nanoparticles act as an efficient algae harvester because of their adsorption and magnetic properties. The method presented in this study demonstrates the wide scope for the use of covalently functionalized core-shell nanoparticles for the production of liquid transportation fuels from algal biomass.
成功合成了用强碱三氮杂双环癸烯（TBD）功能化的核壳型Fe3O4@二氧化硅磁性纳米颗粒，用于收获微藻并实现一锅法将微藻转化为脂肪酸甲酯（FAME，即所谓的生物柴油）。使用了三种藻类油源（即干藻、藻油和藻浓缩物），并优化了反应条件以实现最大生物柴油产率。本研究获得的结果表明，我们的TBD功能化Fe3O4@二氧化硅纳米颗粒能够有效地将藻油转化为生物柴油，最大产率为97.1%。此外，TBD-Fe3O4@二氧化硅纳米颗粒由于其吸附和磁性而成为高效的藻类收获剂。本研究提出的方法证明了共价功能化核壳纳米颗粒在利用藻类生物质生产液体运输燃料方面的广泛应用前景。
