The main purpose of the current research work is to design competent heterogeneous catalyst for the development of sustainable biodiesel technology. Therefore, a novel and an efficient Na-SiO₂@CeO₂ heterogeneous catalyst was designed for sustainable and eco-friendly biodiesel production using wild olive oil as a new and potentially non-edible feedstock. The designed catalyst was further characterized by using FT-IR, BET-BJH, SEM, EDX, XPS and XRD spectroscopic techniques. The experimental results demonstrated that the synthesized catalyst appeared to be efficient for the conversion of wild olive oil to biodiesel, providing maximum yield of 97% at optimum reaction conditions: catalyst concentration 2.5w/w%, reaction duration 120 min, reaction temperature 65 °C, and oil/methanol molar ratio 1:10. It was observed from the endurance test that the synthesized catalyst has remarkable catalytic potency upto five consecutive runs, showing profound stability with negligible leaching of the active basic sites from the surface of the catalyst.

当前研究工作的主要目的是为可持续生物柴油技术的发展设计合格的多相催化剂。因此，新型和有效的Na-SiO ₂ @CeO ₂非均相催化剂的设计目的是使用野生橄榄油作为一种新型的，潜在的不可食用原料，以可持续，环保的方式生产生物柴油。通过使用FT-IR，BET-BJH，SEM，EDX，XPS和XRD光谱技术进一步表征了设计的催化剂。实验结果表明，所合成的催化剂似乎能有效地将野生橄榄油转化为生物柴油，在最佳反应条件下提供最高的97％收率：催化剂浓度2.5w / w％，反应时间120分钟，反应温度65° C和油/甲醇的摩尔比为1:10。从耐久试验中观察到，合成的催化剂在连续五个运行中具有显着的催化效能，显示出极好的稳定性，而活性碱性位点从催化剂表面的浸出可忽略不计。
