“…They are built up by the periodic stacking of positively charged di- and trivalent metal hydroxides (M(II), M’(III)), octahedral layers, and negatively charged interlayer galleries consisting of anions (A n− ) and water. As mentioned above, the use of LDH, as a bulk material or support for metal nanoparticles in catalysis, has increased in an exponential manner [ 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. LDH-supported metal nanoparticles have also shown efficient activities towards the 4-NPhOH reduction [ 29 ].…”

Cobalt-aluminum-layered double hydroxides containing carboxymethyl β-cyclodextrin (CMβCD) were synthesized by coprecipitation and evaluated as a cobalt source for the 4-nitrophenol reduction in an aqueous medium. Several physicochemical techniques (XRD, FTIR, TGA) indicated the intercalation of the anionic cyclodextrin without damages to the hydrotalcite-type structure. These lamellar cobalt-aluminum hybrid materials (CoAl_CMβCD) were evaluated in the 4-nitrophenol reduction and showed higher activities in comparison with the CMβCD-free standard material (CoAl_CO3). To rationalize these results, a set of experimental controls going from physical mixtures of CoAl_CO3 with different cyclodextrins to other cobalt-based materials were investigated, highlighting the beneficial effects of both the layered double hydroxide and CMβCD-based hybrid structures. CMβCD also showed a beneficial effect as an additive during the 4-nitrophenol reduction. CoAl_CO3, dispersed in a fresh CMβCD solution could be re-used for five successive cycles without the loss of activity.

Layered 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.
