摘要

The need for sustainable and eco-friendly fuel alternatives has grown due to practical considerations in recent years. Biodiesel has garnered significant interest as a promising petroleum diesel substitute due to its renewability, biodegradability, and free of sulfur. However, developing advanced and highly efficient heterogeneous catalysts is crucial in the biodiesel production. Among various heterogeneous catalysts, metal–organic frameworks (MOFs) have become the key catalytic materials because of their distinctive and fascinating characteristics. Among the currently explored MOFs, ZIFs have undergone many studies, including catalysis, separation, and sensing, owing their simple and fast preparation process, ultrahigh surface areas, and well-defined active sites. In this review article, the current advances of different types of MOF-based catalysts to accelerate biodiesel production have been discussed. More importantly, it aims to summarize critically the performance, characterization, and reusability of various ZIFs-based catalysts (single ZIFs catalysts, supported ZIFs-based catalysts, and ZIFs-derived catalysts) in catalyzing the production of sustainable biodiesel. Finally, the limitations, the challenges, and future developments of ZIFs-based hybrid catalysts are also proposed, hoping that this timely review can be useful for researchers in promoting sustainable biodiesel generation and other relevant biorefineries using ZIFs-based catalysts.
