“…As expected, the BHMF yield gradually increased as the electrolysis potential became more negative, but after −1.9 V vs. Ag/AgCl (−1.16 V vs. RHE), a more negative electrolysis potential led to little improvement in the BHMF yield. Some studies had attempted to explain the mechanism of how electrolysis potential influenced the electrocatalytic hydrogenation of furfural, which had a similar molecular structure to HMF . It was generally accepted that the surface coverage of the chemisorbed hydrogens (H ads ) on the active sites increased as the electrolysis potential became more negative before saturation, while the hydrogenation reaction between adsorbed furfural and H ads was not largely affected by the electrolysis potential.…”

The hydrogenation of 5‐hydroxymethylfurfural (HMF), an important bio‐based platform chemical, to 2,5‐bis(hydroxymethyl)furan (BHMF), a promising building block for polymers, is conventionally conducted at high pressures of H2 in the presence of heterogeneous catalysts. Recently, electrochemical hydrogenation has emerged as a promising process for BHMF production; however, one challenge of this process is to improve the catalytic activity of the electrocatalyst. In this study, a series of AgCu electrocatalysts was prepared by galvanic displacement of Ag on nanotextured Cu particles. A comprehensive characterization of the catalysts was carried out and the effects of electrolysis potential, reaction time, and HMF concentration were investigated. The concentration of AgNO3 solution in which Cu was displaced was found to be a key factor to control the catalyst surface morphology, and the optimal catalyst was shown to have high catalytic activity and excellent stability for the electrochemical hydrogenation of HMF to BHMF.

BACKGROUND Furfuryl alcohol (FOL) is an upgraded product from biomass‐based furfural (FAL), which has wide application in fine chemical and polymer industries. FOL can be produced by chemical approaches, but harsh reaction conditions and subsequent safety problems often pose considerable challenges for chemical methods. In contrast to chemical methods that often do not meet the requirement for green chemistry, bio‐catalysis is an attractive alternative to replace chemical methods due to its mild reaction conditions and environmental friendliness. However, FAL is a well‐known inhibitor of many microorganisms. In this study, four different wild‐type cells were screened and employed for the bioreduction of FAL to FOL using a whole‐cell system. RESULTS Among these strains, Saccharomyces cerevisiae NL22 exhibited the best transformation ability from FAL into FOL. In order to improve the conversion of FAL and selectivity of FOL, optimization of whole‐cell biotransformation using S. cerevisiae NL22 was carried out. A maximal conversion of 98% and a high selectivity of 87.9% were obtained at 30 °C and 62 mmol L−1 FAL in the presence of 1.3 mol glucose/mol FAL within 8 h. A total of 122 mmol L−1 FOL was synthesized within 24 h reaction by a fed‐batch strategy. CONCLUSION The bioprocess developed in this study is a highly efficient method for FOL synthesis. The wild‐type strain S. cerevisiae NL22 might serve as a candidate for the production of FAL to FOL as an efficient biocatalyst. © 2019 Society of Chemical Industry

“…FFA is mainly produced by the gas‐phase or liquid‐phase hydrogenation of FFR. Metals such as Cu, Co, Ni, Ru, Rh, Pd, and Pt are normally chosen as active components for this hydrogenation. Among them, the copper‐chromite (Cu‐Cr) catalyst has been the most commercially successful for decades.…”

A series of Cu/TiO2‐SiO2 catalysts were prepared by a sol‐gel hydrothermal method and characterized by BET, SEM, TEM, XRD, XPS, and H2‐TPR. The catalysts were used for selective hydrogenation of furfural to furfuryl alcohol. Results show that based on the Cu/SiO2 catalyst, introducing a part of TiO2 into the carrier while keeping very large specific surface area would promote the reduction of CuO, inhibit the growth of Cu crystal particles, and improve the dispersity of Cu particles in the catalyst. The electronegativity of Cu is enhanced in the double‐loaded Cu/TiO2‐SiO2 catalyst, compared with single‐loaded Cu/SiO2 or Cu/TiO2 catalysts. The Cu/TiO2‐SiO2 catalyst containing 0.40 g/g (40 wt%) TiO2 in the carrier shows high furfural hydrogenation performance.
