Biodiesel considered a green, environmentally friendly, and renewable energy source is one of the most promising candidates to replace fossil fuels to supply energy for the world. The conventional thermocatalytic methods have been extensively explored for producing biodiesel, while inevitably encountering some drawbacks, such as harsh operating conditions and high energy consumption. The catalytic production of biodiesel under mild conditions is a research hotspot but with difficulty. Photocatalysis has recently been highlighted as an eco-friendly and energy-saving approach for biodiesel production. This mini-review summarizes typical photocatalysts for biodiesel production and discusses in detail the catalytic mechanism and strategies of the photo-driven (trans)esterification to produce biodiesel. The current challenges and future opportunities of photo-driven catalysis to prepare biodiesel are also outlined, in steps towards guiding the design of advanced photocatalysts for biodiesel production.
生物柴油被认为是一种绿色、环保且可再生的能源，是替代化石燃料为全球提供能源的最有前景的候选者之一。传统的热催化方法已被广泛用于生产生物柴油，但不可避免地存在一些缺点，如苛刻的操作条件和高能耗。在温和条件下催化生产生物柴油是一个研究热点，但存在困难。光催化最近被视为一种用于生物柴油生产的环保节能方法。本综述总结了用于生物柴油生产的典型光催化剂，并详细讨论了光驱动（转）酯化生产生物柴油的催化机理和策略。还概述了光驱动催化制备生物柴油目前面临的挑战和未来机遇，以逐步指导用于生物柴油生产的先进光催化剂的设计。
