Abstract
AbstractLayered double hydroxides (LDH) have significant attention in recent times due to their unique characteristic properties, including layered structure, variable compositions, tunable acidity and basicity, memory effect, and their ability to transform into various kinds of catalysts, which make them desirable for various types of catalytic applications, such as electrocatalysis, photocatalysis, and thermocatalysis. In addition, the upcycling of lignocellulose biomass and its derived compounds has emerged as a promising strategy for the synthesis of valuable products and fine chemicals. The current review focuses on recent advancements in LDH‐based catalysts for biomass conversion reactions. Specifically, this review highlights the structural features and advantages of LDH and LDH‐derived catalysts for biomass conversion reactions, followed by a detailed summary of the different synthesis methods and different strategies used to tailor their properties. Subsequently, LDH‐based catalysts for hydrogenation, oxidation, coupling, and isomerization reactions of biomass‐derived molecules are critically summarized in a very detailed manner. The review concludes with a discussion on future research directions in this field which anticipates that further exploration of LDH‐based catalysts and integration of cutting‐edge technologies into biomass conversion reactions hold promise for addressing future energy challenges, potentially leading to a carbon‐neutral or carbon‐positive future.
