“…Ebitani et al [86] achieved the highly selective preparation of glyceric acid by using hydrotalcitesupported platinum catalyst under mild conditions (60 °C). Wei et al [87] synthesized the rehydrated Pt/hydrotalcite catalyst by impregnation-reduction and in situ rehydration method. XRD and TEM analyses showed that Pt particles were uniformly distributed in re-Pt/HT, and the layered structure of hydrotalcite was restored.…”

“…Another classical system is the catalytic oxidation of glycerol to glyceric acid. In the work reported by Wei et al [87], a series of Pt-HT catalysts was prepared through wet impregnation and in situ rehydration procedure. To investigate the metal-support interaction and structure-activity relationship in this system, the researchers carried out a combination study including in situ FT-IR spectroscopy, X-ray absorption fine structure spectroscopy, H 2 -TPR, and catalytic evaluations to confirm the significant role of electron-deficient Pt d+ species in the enhancement of catalytic activities via enhancing the C-H bond cleavage (Fig.…”

With the world’s fossil fuels being finite in nature, an increasing interest focuses on the application of alternative renewable resources such as biomass. Biomass-derived platform chemicals with abundant functional groups have the potential to replace bulk chemicals for the production of value-added chemicals, fuels, and materials. The upgrading of these platform chemicals relies on the development of efficient catalytic systems. Hydrotalcite, with its wide compositional variety, tuneable anion-exchange capacity, and controlled acidity/basicity sites demonstrates great potential in the catalytic upgrading of biomass and the derived platform chemicals. The past decade has witnessed the emergence of research achievements on the development of efficient and robust hydrotalcite-derived metal catalysts and their applications in the upgrading of biomass or the derived platform chemicals. In this review, we aim to summarize the recent advances on the catalytic upgrading of biomass-derived platform chemicals (e.g., furfural, 5-hydroxymethylfurfural, levulinic acid, and glycerol) via hydrotalcite-derived metal catalysts. We also observed that the crucial role of using hydrotalcite-derived catalysts relies on their strong metal–support interactions. As a result, a section focusing on the discussion of the metal–support interactions of hydrotalcite-derived catalysts was provided.

“…Many reactions (e.g., biomass conversions and organic syntheses) using solid acid/base catalysts are attracting much attention as an effective approach to obtain high reaction rate and catalytic selectivity (Figure A). − Hence, a comprehensive cognition on the acid and base natures of heterogeneous catalysts will provide deep insight into rational design of highly efficient catalysts. By virtue of the specific synergy of structure properties in LDHs precursors (including the regulation of both guest anions and host layers, topological structural transformation, as well as memory effect), the strength and concentration of surface acid and base sites of LDHs-derived catalysts can be modulated for the desired goals. , …”

Heterogeneous upgrading reactions serve as a promising and pivotal strategy for efficient utilization of biomass resources for chemical energy, fuel, and hydrogen, in which supported catalysts play a key role in determining catalytic activity and selectivity for desirable products. Biomass is the only renewable organic carbon resource in nature, and its conversion (e.g., hydrogenation, hydrodeoxygenation, oxidation, alkylation, halogenation, or nitration) to a variety of chemical intermediates and feedstocks has attracted increasing attention in fundamental investigations and industrial productions. The efficiency of heterogeneous catalysts in the above catalytic conversion highly rests with the properties of metals, supports, and additives, as well as reactors and reaction conditions (solvent, pressure, and temperature). Recently, multifunctional catalysts derived from layered double hydroxides (LDHs) precursors have displayed outstanding catalytic performance, which made a great contribution to the development on high-value upgrading reactions of biomass resources. The elaborate regulation of surface and interface structure, geometric and electronic structure, defect and coordination structure of catalysts via tuning the chemical composition, structural architecture, and topotactic transformation process of LDHs precursors imposes a significant influence on the resulting catalytic behavior. Moreover, the detailed investigations on structure−property relationship by virtue of comprehensive studies provide innovative strategies for the synthesis of highefficiency LDHs-derived catalysts with desirable characteristics. In this Perspective, on the basis of achievement in the representative studies, we put forward some suggestions and prospects for upgrading reactions of biomass resources in the future.

“…Furthermore, both hydrotalcites and the mixed metal oxides can exhibit abundant surface-tunable basic sites. [1,2] These features together have greatly broadened their applications in diverse fields as adsorbents, [3][4][5] ion-exchangers, [6][7][8] or catalyst carriers [9][10][11][12][13][14] and base catalysts. [15][16][17][18][19][20] Among the diverse families of the hydrotalcites, magnesium and alumina hydrotalcites are among the most widely studied materials in the literature.…”

“…[30] For instance, significantly different activities of hydrotalcites in the transesterification reactions have been reported by different research groups. [19,20] On the other hand, the hydrotalcites have been used as carriers for the metal supported catalysts [10][11][12][13][14] and in this case, the residual alkali metals might act as a promoter. In fact, the minute of alkali metals might significantly affect the electronic properties of the metal supported catalysts and thus their catalytic performance can be altered as well.…”

The structural evolution of classic coprecipitation-derived MgÀ Al mixed oxide (MMO) upon doping of different alkali metals in a wide level (1-20 wt.%) was revisited. The pristine lateral MMO of aggregates into particulates, accompanied with the dramatic loss of the surface areas and the formation of aluminates. These phenomena become severer with the decrease of the atomic radius. The formation of NaAlO 2 likely occurs via the gradual dealumination of the MMO, which is highly dependent on both the dopant content and the activation temperature. This leads to ultimately a new ensemble with MgO as the core decorated by NaAlO 2 in the outer surfaces at high Na doping level and above 973 K. When evaluated in the base-catalyzed transesterification and acylation model reactions, the Na-doped MMO show enhanced performance and a plateau at increasing doping that might be explained by an interplay between the number and strength of strong basicity.
