Abstract Exploration of non-edible oil as a feedstock and the use of new heterogeneous nanocatalyst could contribute to bioenergy research. In this regard, the present work is focussed on the use of cobalt doped zinc oxide nanocatalyst for production of biodiesel from Mesua ferrea oil. The synthesized catalyst has been analyzed through X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), and Thermogravimetric analysis (TGA) techniques. Under optimal reaction condition, maximum biodiesel conversion of 98.03% was obtained in 3 h at 60 °C with 2.5 wt% catalyst loading and 1:9 oil to methanol molar ratio. The produced biodiesel has been characterized using Proton Nuclear Magnetic Resonance (1H NMR), Carbon Nuclear Magnetic Resonance (13C NMR) and Gas Chromatography-Mass Spectroscopy (GC-MS) techniques. Fuel properties of the produced biodiesel have also been determined. The result showed good catalytic activity of cobalt doped Zinc oxide nanocatalyst and could be used for large scale biodiesel production from Mesua ferrea oil by further enhancing its stability.

Co掺杂ZnO作为非食用油生产生物柴油的多相纳米催化剂的合成及应用

摘要 以非食用油为原料的探索和新型多相纳米催化剂的使用有助于生物能源研究。在这方面，目前的工作重点是使用钴掺杂氧化锌纳米催化剂从 Mesua ferrea 油生产生物柴油。合成的催化剂已通过 X 射线衍射 (XRD)、傅里叶变换红外光谱 (FT-IR)、扫描电子显微镜 (SEM)、能量色散 X 射线 (EDX) 和热重分析 (TGA) 技术进行分析。在最佳反应条件下，当催化剂负载量为 2.5 wt% 和油甲醇摩尔比为 1:9 时，60 °C 下 3 小时内生物柴油的最大转化率为 98.03%。所生产的生物柴油已使用质子核磁共振 (1H NMR) 进行表征，碳核磁共振 (13C NMR) 和气相色谱-质谱 (GC-MS) 技术。生产的生物柴油的燃料特性也已确定。结果表明，钴掺杂氧化锌纳米催化剂具有良好的催化活性，可通过进一步提高其稳定性，用于从 Mesua ferrea 油中大规模生产生物柴油。
