“…[35,36] Fu and coworkers used Ni-tungsten carbide and perovskite-type oxide supported Ni catalysts for the conversion of HMF into DMF. [45] The key issue for these promising Cu-and Ni-based catalysts ystemsi sh ow to suppress the overhydrogenation of the aromatic furan ring and the ring-opening of DMF to improve the selectivity towards DMF. [39][40][41][42] They also studied the one-step continuous conversiono ff ructoset o DMF over combined HY zeolite and HT-Cu/ZnO/Al 2 O 3 in af ixed-bed reactor with aD MF yield of 40.6 %.…”

This work provided the first example of selective hydrodeoxygenation of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF) over heterogeneous Fe catalysts. A catalyst prepared by the pyrolysis of an Fe-phenanthroline complex on activated carbon at 800 °C was demonstrated to be the most active heterogeneous Fe catalyst. Under the optimal reaction conditions, complete conversion of HMF was achieved with 86.2 % selectivity to DMF. The reaction pathway was investigated thoroughly, and the hydrogenation of the C=O bond in HMF was demonstrated to be the rate-determining step during the hydrodeoxygenation, which could be accelerated greatly by using alcohol solvents as additional H-donors. The excellent stability of the Fe catalyst, which was probably a result of the well-preserved active species and the pore structure of the Fe catalyst in the presence of H , was demonstrated in batch and continuous flow fixed-bed reactors.

“…This was due to the copper mesh used as sample support for TEM analysis. (Figure d). In contrast, for Co 5 Cu 2 ‐C sample prepared without addition of a nitrogen‐containing ligand, the size of the bimetallic nanoparticles is relatively large, and the diameter of the metal particles was approximately 30 nm to 40 nm (as shown in Figure e).…”

The non‐precious metal catalysts with high catalytic activity is extremely desirable but still full of challenges. In this paper, CoCu bimetal immobilized on nitrogen‐doped porous carbon (CoCu‐N‐C) was prepared by an effective ligand‐stabilized pyrolysis strategy. CoCu‐N‐C exhibited excellent catalytic efficiency for the transfer hydrogenation of nitroarenes with ammonia borane as hydrogen source, which can be ascribed to the well dispersed metal nanoparticles, the synergetic interaction of CoCu bimetal and nitrogen‐doped carbon. The durability and recyclability experiments of the recycled CoCu‐N‐C catalyst indicated that no obvious change in catalytic performance was observed after five consecutive cycles. To gain insight into the catalytic mechanism of CoCu‐N‐C for the hydrogenation reaction, density functional theory calculations was also conducted. This work provides an universal approach for constructing highly efficient non‐precious metal heterogeneous catalysts and which may find diverse high performance applications.

Abstract:There is growing interest in the use of furans, a class of alternative fuels derived from biomass, as transportation fuels. This paper reviews recent progress in the characterization of its combustion properties. It reviews their production processes, theoretical kinetic explorations and fundamental combustion properties. The theoretical efforts are focused on the mechanistic pathways for furan decomposition and oxidation, as well as the development of detailed chemical kinetic models. The experiments reviewed are mostly concerned with the temporal evolutions of homogeneous reactors and the propagation of laminar flames. The main thrust in homogeneous reactors is to determine global chemical time scales such as ignition delay times. Some studies have adopted a comparative approach to bring out reactivity differences. Chemical kinetic models with varying degrees of predictive success have been established. Experiments have revealed the relative behavior of their combustion. The growing body of literature in this area of combustion chemistry of alternative fuels shows a great potential for these fuels in terms of sustainable production and engine performance. However, these studies raise further questions regarding the chemical interactions of furans with other hydrocarbons. There are also open questions about the toxicity of the byproducts of combustion.
