“…Aldol condensation is another example of important organic reactions for biomass upgrading, in particular, to fuels [136] . Recently, a greener synthesis route by employing the impregnation technique instead of the common co-precipitation technique has been used for the synthesis of hydrotalcite and resulted in an efficient catalytic system with adequate Brønsted acidity for aldol condensation reaction of furfural with acetone [137] . Glycerol steam reforming is an alternative catalytic route for upgrading biomass-derived glycerol.…”

Hydrotalcites are inorganic layered materials which have been used in a wide spectrum of applications from catalysis and adsorption to heavy metals immobilization and polymer stabilization. Apart from this, they can act as drug carriers or acid scavengers. More recently, due to the urgent need for developing functional materials required in the production of renewable fuels and chemicals, hydrotalcites have been increasingly noticed as versatile compounds. For instance, they are applicable in biofuel synthesis, biomass upgrading, plastics degradation, hydrogen storage and so forth. In addition, they are cost-efficient materials and thus beneficial for the realization of the above-mentioned applications on the industrial scale. It is noteworthy that for further development of novel hydrotalcites, validation of their performance and their stability are essential. To elucidate these aspects, the major significance of these materials and their capability for application in various catalytic fields are discussed in this survey. Particular focus is given to their most recent utilization in sustainable and green applications.

Hydrotalcite materials (HTs) were synthesized by a facile and swift combined mechanochemistry/coprecipitation approach, and their catalytic activity was evaluated and compared with conventionally synthesized hydrotalcites (co-precipitation method) in the Knoevenagel condensation between furfural and ethyl cyanoacetate/malononitrile. Characterization and catalytic activity results clearly demonstrate that the proposed combined mechanochemical/coprecipitation approach provides an improvement in crystallinity, morphology, tunable basicity, and textural properties (higher surface area and enhanced surface properties) as compared to HTs obtained via conventional coprecipitation methods. In addition, mechanochemically synthesized HTs largely improve catalytic activities, including conversion and product selectivity to Knoevenagel condensation products under solventless conditions, short reaction times, or reaction at room temperature as compared to conventional counterparts (e.g., 30–40 vs > 99% product yields).
