Biodiesel is one of the main biofuels used to replace fossil resources, and is mainly produced from esterification and transesterification of fatty acids and oils catalyzed by acids, bases or enzymes. Among the existing catalysts, metal oxides and their derivatives play an important role because of their high catalytic activity and low cost. ZnO is a metal oxide and its related nanomaterials are easy to prepare, which gives ZnO superior reactivity and extensive applications. Suitably modified ZnO nanomaterials typically have high specific surface areas, suitable pore sizes, and enhanced catalytic performance in the production of biodiesel. The present review introduces the application progress of ZnO catalysts in biodiesel preparation. The current shortcomings and future challenges of the basic heterogeneous catalytic systems for biodiesel production are also discussed.
生物柴油是用于替代化石资源的主要生物燃料之一,主要由酸、碱或酶催化脂肪酸和油脂的酯化及酯交换反应制得。在现有的催化剂中,金属氧化物及其衍生物因其高催化活性和低成本而发挥着重要作用。氧化锌是一种金属氧化物,其相关纳米材料易于制备,这赋予了氧化锌优异的反应活性和广泛的应用。经过适当改性的氧化锌纳米材料通常具有高比表面积、合适的孔径,并在生物柴油生产中具有增强的催化性能。本综述介绍了氧化锌催化剂在生物柴油制备中的应用进展。还讨论了生物柴油生产基本多相催化体系当前存在的不足和未来面临的挑战。
