“…In addition, the particle size was found to be of paramount importance in the reaction since Ni−Cu−OMA, the catalyst with the smallest particle size, provided the best performance. Previous studies have also reported that smaller particle sizes are favorable for LA conversion reactions [51–53] …”

“…Previous studies have also reported that smaller particle sizes are favorable for LA conversion reactions. [51][52][53] Furthermore, the synergistic effect of Ni and Cu was greatly affected by the fabrication strategy, which influenced the interfacial properties of Ni and Cu. The H 2 -TPR results indicated that a NiÀ Cu alloy might have been formed during the preparation of NiÀ CuÀ OMA, indicating that the Ni and Cu species were simultaneously reduced to generate the NiÀ Cu alloy of the Ni δ Cu 1-δ Al 2 O 4 (0 � δ � 1) form.…”

In this work, three types of alumina‐supported bimetallic Ni−Cu catalysts [Ni−Cu/commercial non‐ordered mesoporous alumina (CMA), Ni−Cu/ordered MA (OMA), and Ni−Cu−OMA] were prepared via different fabrication strategies and investigated in the conversion of levulinic acid (LA) into γ‐valerolactone and 2‐methyltetrahydrofuran (2‐MTHF). This study employed characterization techniques and reactions to reveal the effects of the fabrication strategy on the activities of the catalysts. It was observed that the catalysts constructed on OM supports (Ni−Cu/OMA and Ni−Cu−OMA) displayed superior catalytic performance compared to those constructed on CM supports (Ni−Cu/CMA). Specifically, Ni−Cu−OMA, which was fabricated via the one‐pot evaporation‐induced self‐assembly strategy, exhibited the best catalytic performance, achieving a complete conversion of LA and a high selectivity of 73.0 % toward 2‐MTHF in a solvent‐free reaction environment. The promising activity of Ni−Cu−OMA was ascribed to the well‐dispersed active sites within the framework of the support, the enhanced metal‐support interaction, and the highly efficient exploitation of the synergistic effect between Ni and Cu. Detailed post‐characterization techniques were also employed to highlight the outstanding stability of Ni−Cu−OMA.

“…However, it has an energetic density and cetane numbers lower than fossils fuels; therefore it has been studied more as an additive to fuels [17,18]. Moreover, it can be used as solvent to process the biomass, because it is able to dissolve biomass fractions avoiding the use of expensive solvents, enzymes or ionic liquids [19][20][21].…”

Mesoporous materials have found wide application as catalyst supports. In this study, we have shown that Ru nanoparticles supported on SBA-15 are highly active toward hydrogenation of biomass-derived ethyl levulinate (EL) even at room temperature. A series of Ru loaded SBA-15 (xRu-SBA-15, x = 1, 3, and 5 wt% Ru) were prepared by a deposition-precipitation method and further reduced with NaBH 4 . TEM images suggest that the reduction with NaBH 4 led to the formation of Ru particle with size in range of 1-2 nm. These nely distributed Ru nanoparticles on SBA-15 showed high activity for hydrogenation of C = O group of EL at room temperature and low H 2 pressure (0.5 MPa), with ethyl hydroxyl pentanonate (EHP) selectivity of 97%. Kinetics study showed that the Ru nanoparticles in proper size (2.1 ± 0.1 nm) gave a low apparent activation energy (Ea) about 20 kJ/mol for C = O hydrogenation. Moreover, 3Ru-SBA-15 displayed a good reusability, on which the EL conversion remained stable (~ 80%) after six recycles. The produced EHP could be further converted to gamma valerolactone (GVL) over HZMS-5 e ciently upon thermal treatment.
