Abstract A highly efficient and green process for the hydrogenation of biomass‐derived levulinic acid (LA) to γ‐valerolactone (GVL) has been developed. GVL was obtained in a yield 99.9 mol % with turnover frequency as high 7676 h −1 aqueous medium by using Ru/TiO 2 catalyst under mild reaction conditions (70 °C). The strong interaction between Ru TiO facilitated both dispersion nanoparticles stability catalyst. In addition, solvent, water participated LA, which confirmed an isotope‐ labeling...
Low-temperature efficient hydrogenation of C═O bonds in various compounds, which is one the most important processes for producing fuels and chemicals, fundamental interest but remains a significant challenge. The primary problem lack heterogeneous catalyst systems that are highly active at ambient or low temperatures. This paper describes an strategy designing low-temperature catalyst. Ru nanoparticles supported on reduced graphene oxide (Ru/RGO) show remarkable efficiency levulinic acid...

Abstract One‐step direct conversion of biomass‐derived furfural to 2‐methyltetrahydrofuran was realized under atmospheric pressure over a dual solid catalyst based on two‐stage‐packed Cu–Pd in reactor; this is the first report that one‐step resulted high yield (97.1 %) pressure. This strategy provided successive hydrogenation process, which avoids H 2 pressure, uses reactor efficiently, and eliminates product‐separation step. Therefore, it could enhance overall efficiency as result low cost yield.
To develop the high-performance supported metal catalyst for industrial processes, it is highly desirable to elucidate and fully utilize indispensable support part. Herein, relationship between catalytic performance structure of ZrO2 was elucidated by comprehensive analysis progressive calcination experiments, tests over model catalysts, various characterizations structures. We demonstrated that combination Cu tetragonal makes a active, selective, especially stable hydrogenation dimethyl...
Abstract A highly efficient and green process was developed for direct conversion of levulinic acid into 1,4‐pentanediol over Mo‐modified Ru/activated carbon (AC) catalyst in a continuous fixed‐bed reactor. The Ru–MoO x /AC found to be the aqueous‐phase hydrogenation 1,4‐pentanediol, whereby high yield (96.7 mol %) obtained under mild reaction conditions (70 °C, 4 MPa H 2 ).
Aqueous hydrogenation of 5-hydroxymethylfurfural (HMF) was performed over the RuPd/graphene (RGO) bimetallic catalyst at room temperature (20 °C). The combination Pd and Ru gave best catalytic performance for complete HMF to 2,5-dihydroxymethyltetrahydrofuran (DHMTHF) compared with corresponding monometallic Ru/RGO Pd/RGO catalysts. yield DHMTHF reached 92.9% RuPd/RGO catalyst, while it 6.0% 4.1% respectively. High-resolution TEM (HRTEM), high-angle annular dark-field STEM (HAADF-STEM),...

Selective conversion of fructose to fuels and fine chemicals is an important step for biomass utilization. In this paper, direct 2,5-dihydroxymethylfuran 2,5-dimethylfuran was first realized over combined HY zeolite inexpensive hydrotalcite (HT)-Cu/ZnO/Al2O3 in a fixed-bed reactor. The cooperative effect γ-butyrolactone solvent facilitated the dehydration into 5-hydroxymethylfurfural. By adjusting hydrogenation temperature HMF HT-Cu/ZnO/Al2O3 catalyst, high yields (48.2%) at 140 °C (40.6%)...
