Recent advances in the catalytic transfer hydrogenation of furfural to furfuryl alcohol over heterogeneous catalysts

Abstract

Catalytic transfer hydrogenation (CTH) is recently emerged as a highly attractive approach to achieve biomass-based hydrogenation due to the free of high-pressure fossil-derived H2 and potentially reduced process cost. As...

A high-efficiency zirconium-based single-atom catalyst for the transformation of biomass-derived 5 hydroxymethylfurfural to 2,5-bis(hydroxymethyl)furan with nearly 100% selectivity

“…S11, † compared with the normal experiment without any additive, when KSCN and HCOOH were used to poison the Lewis acid site (Zr) and Lewis base site ( pyridinic-N), respectively, a blindingly obvious decrease in HMF conversion and BHMF yield was observed, indicating that both Zr and pyridinic-N were definitely needed and their synergistic effects were the key to guarantee the smooth proceeding of TH. Based on the above experimental results and relevant literatures, 52,54,62,86,[90][91][92] an evidential reaction mechanism for the TH of HMF to BHMF in iPrOH over Zr/NC is proposed in Fig. 9.…”

Magnetic Nanoparticles Supported on g‐C3N4 : An Efficient Heterogeneous Catalyst for Selective Transfer Hydrogenation of Furfural to Furfuryl alcohol

“…However, non-noble metal catalysed conventional liquid-phase hydrogenation continues to demand elevated hydrogen pressure thus making this process more costly. [19,20] Nonetheless, considerable attempts have recently been made for the generation of "green hydrogen" through water splitting or biomass gasification yet most of the industrially produced hydrogen is obtained from inextensible fossil resources. [6,21,22] In the light of these facts, catalytic transfer hydrogenation (CTH) of furfural has recently encountered as a substitutional excess for the reduction of biomass derived molecules.…”

“…Therefore, a lots of chromium‐free catalysts are synthesised to accomplish an environmentally favourable hydrogenation of FF to FFA. However, non‐noble metal catalysed conventional liquid‐phase hydrogenation continues to demand elevated hydrogen pressure thus making this process more costly [19,20] . Nonetheless, considerable attempts have recently been made for the generation of “green hydrogen” through water splitting or biomass gasification yet most of the industrially produced hydrogen is obtained from inextensible fossil resources [6,21,22] …”

Highly Efficient Transfer Hydrogenation of Biomass-Derived Furfural to Furfuryl Alcohol over Mesoporous Zr-Containing Hybrids with 5-Sulfosalicylic Acid as a Ligand

“…Accordingly, 5-sulfosalicylic acid is expected to be closely coordinated with zirconium ions. Aside from the close interaction of organic ligands with zirconium ions, a high surface area and large pore volume are also needed to improve the exposure of active sites [ 29 ]. Moreover, mesopores in the hybrids are commonly thought to be favorable to mass transfer in the liquid phase reaction [ 30 ].…”
