“…It is generally accepted that defect sites may significantly impact the catalytic hydrogenation performance of a catalyst, and oxygen vacancies are common characteristics . The surface Mn 2+ −O v −Mn 2+ defect of CuMn− x catalysts can promote the hydrogenation of dimethyl succinate through interaction with the carbonyl group and then weaken the C=O bond . Furthermore, Mudiyanselage et al.…”

Various Cu/CeO2 nanorod catalysts with different copper contents were synthesized through a facile coprecipitation method for the hydrogenation of diethyl carbonate to methanol in a fixed‐bed reactor. The methanol yield increased upon increasing the copper loading, but large excess amounts of copper led to deactivation of the catalyst at a high liquid hourly space velocity because of aggregation of the active metal. The 20Cu/CeO2 and 30Cu/CeO2 catalysts displayed superior catalytic performance with methanol space‐time yields of 8.4 and 8.1 mmol gcat−1 h−1, respectively. The remarkably enhanced catalytic performance was mainly ascribed to a high Cu0 surface area, appropriate ratio of Cu+/Cu0, and more surface oxygen vacancies associated with Ce3+, which stemmed from a strong interaction between Cu and the CeO2 support.

“…Hydrogenolysis of tartaric acid also produces succinic acid as a major product . The chemistry and catalysis involved in production of succinic acid, and further conversion to GBL, THF and 1,4‐BDO have been summarized in several reviews (Scheme ) –. The hydrogenation of succinic acid is emerging as an attractive route for synthesis of commodity chemicals such as C 4 alcohols and diols.…”

Conversion of biomass to chemicals provides essential products to human society from renewable resources. In this context, achieving atom‐economical and energy‐efficient conversion with high selectivity towards target products remains a key challenge. Recent developments in nanostructured catalysts address this challenge reporting remarkable performances in shape and morphology dependent catalysis by metals on nano scale in energy and environmental applications. In this review, most recent advances in synthesis of heterogeneous nanomaterials, surface characterization and catalytic performances for hydrogenation and oxidation for biorenewables with plausible mechanism have been discussed. The perspectives obtained from this review paper will provide insights into rational design of active, selective and stable catalytic materials for sustainable production of value‐added chemicals from biomass resources.

“…145 Despite the fact that the catalyst was optimized for the hydrogenation of dimethyl succinate to γ-butyrolactone, it shows an excellent catalytic performance towards the selective hydrogenation of levulinic acid achieving a total conversion and 100% selectivity to GVL at 210°C, 0. by the CvO group, thus forming a C-O σ bond. Correspondingly, the oxygen vacancy linked to Mn 2+ can be occupied by the oxygen atom of the C-O σ bond.…”

Recent advances on the utilization of layered double hydroxides (LDHs) and related heterogeneous catalysts in a lignocellulosic-feedstock biorefinery scheme

Layered double hydroxides (LDHs) and derived materials have been widely used as heterogeneous catalysts for different types of reactions either in gas or in liquid phase. Among these processes, the valorization/upgrading of lignocellulosic biomass and derived molecules have attracted enormous attention because it constitutes a pivotal axis in the transition from an economic model based on fossil resources to one based on renewable biomass resources with preference for biomass waste streams. Proof of this is the increasing amount of literature reports regarding the rational design and implementation of LDHs and related materials in catalytic processes such as: depolymerization, hydrogenation, selective oxidations, and C-C coupling reactions, among others, where biomass-derived compounds are used. The major aim of this contribution is to situate the most recent advances on the implementation of these types of catalysts into a lignocellulosic-feedstock biorefinery scheme, highlighting the versatility of LDHs and derived materials as multifunctional, tunable, cheap and easy to produce heterogeneous catalysts.
