Due to diminishing fossil fuel supplies and rising energy needs, there has been an ever-increasing demand for renewable energy sources. The available renewable energy resources, such as solar, wind, hydropower, and biofuels, provide a new way of supplying the world's energy needs. Biofuels stand out among them because they are sustainable and have the potential to bring the idea of a global bioeconomy to life. As a result of their production of biofuels like biomethane, biohydrogen, and biodiesel, atmospheric CO is being fixed, eventually lowering the world's carbon footprint. Current developments in the production of bioenergy have concentrated on producing biodiesel among other biofuels. Biodiesel is being produced from a variety of feedstocks using a number of processes, including transesterification, micro-emulsion, direct mixing, and pyrolysis. The most popular method among these is transesterification, which makes use of a variety of catalysts. As a result of the development of nanotechnology, nanocatalysts with desirable properties, such as increased catalytic activity, increased surface area, and superior thermal stability, have been made and modified. In this review, various nanocatalyst types and manufacturing processes are examined in relation to transesterification. It explores how crucial nanocatalysts are in boosting biodiesel production, highlights potential barriers, and makes recommendations for their widespread use in the future.
由于化石燃料供应的减少和能源需求的不断增加，对可再生能源的需求一直在持续增长。现有的可再生能源资源，如太阳能、风能、水能和生物燃料，为满足全球能源需求提供了新途径。生物燃料在这些资源中脱颖而出，因为它们具有可持续性，并且有可能将全球生物经济的理念变为现实。由于生物甲烷、生物氢和生物柴油等生物燃料的生产，大气中的二氧化碳正在被固定，最终降低了全球的碳足迹。目前生物能源生产的发展主要集中在生产生物柴油以及其他生物燃料上。生物柴油是通过多种原料，采用包括酯交换、微乳液、直接混合和热解等多种工艺生产的。其中最常用的方法是酯交换法，它使用了多种催化剂。由于纳米技术的发展，已经制备并改性了具有理想性能的纳米催化剂，如提高催化活性、增加表面积和具有优异的热稳定性。在这篇综述中，研究了与酯交换反应相关的各种纳米催化剂类型和制造工艺。探讨了纳米催化剂在提高生物柴油产量方面的关键作用，强调了潜在的障碍，并对其未来的广泛应用提出了建议。
