“…The peaks at 1320 cm −1 and 1590 cm −1 in the Raman spectra correspond to carbon defects (D band) and graphitization (G band), respectively. [ 36,37 ] The analysis results show that the I D / I G increases first and then decreases with the increase of sulfate ion content in the preparation process (Figure S6, Supporting Information). This is because appropriate sulfate ions promote the increase in pore size and S doping in the sample at high temperature, resulting in an increase in defects.…”

To improve the catalytic activity of the catalysts, it is key to intensifying the intrinsic activity of active sites or increasing the exposure of accessible active sites. In this work, an efficient oxygen reduction electrocatalyst is designed that confines plentiful FeCx nanoclusters with Fe‐N4 sites in a concave porous S‐N co‐doped carbon matrix, readily accessible for the oxygen reduction reaction (ORR). Sulfate ions react with the carbon derived from ZIF‐8 at high temperatures, leading to the shrinkage of the carbon framework and then forming a concave structure with abundant macropores and mesopores with S incorporation. Such an architecture promotes the exposure of active sites and accelerates remote mass transfer. As a result, the catalyst (Fe/S‐NC) with a large number of C‐S‐C, Fe‐N4, and FeCx nanoclusters presents impressive ORR activity and stability. In alkaline media, the half‐wave potential of the best catalyst (Fe/S2‐NC) is 0.91 V, which far exceeds that of commercial platinum carbon (0.85 V), while in acidic media the half‐wave potential reaches 0.784 V, comparable to platinum carbon (0.812 V). Furthermore, for the zinc‐air battery, the outstanding peak power density of Fe/S2‐NC (170 mW cm−2) superior to platinum carbon (108 mW cm−2) also highlights its great application potential.

“…Ni-base catalysts are known to be effective in the hydrogenation of FAL [20]. However, there are two shortcomings in the catalytic hydrogenation of FAL: (1) Ni-base catalysts are excellent in the adsorption and activation of H 2 , but the activated H* and the formed intermediates are hard to desorb from the surface of Ni, which will slow the subsequent hydrogenation [21]. (2) A flat adsorption mode of FAL on Ni surface will promote the adsorption and activation of both C=C bond on furan ring and C=O bond, resulting in the total hydrogenation of FAL to THFA [22].…”

“…Alloys formation also influence at selectivity and activity of catalysts for furfural hydrogenation. Recently, was suggested an alloy chemistry strategy to modify the d-band center of Ni by Cu incorporation [51]. These catalysts were prepared by pyrolysis of a metal−organic framework (MOF) precursor containing cooper and nickel (NiCux-BTC).…”

Energy and the environment will always play key roles in society. The climate emergency cannot be ruled out to enable the transition for a clean energy future. Currently, non-renewable energy resources are declining, therefore is important to continuously explore renewable resources. Biomass is a renewable resource that can be applied to reduce climate changes and to accomplhish emission policies. Cellulose is the most abundant type of biomass worldwide, which can be transformed into biofuels and potential building block platform molecules (e.g furfural) throughout biological or chemical methods. Furfural can be synthetized from cellulose using hydrolysis and dehydration reactions. Furfural has a furan ring and carbonyl functional group which makes it an important intermediary to produce higher value-added molecules at industrial level. These molecules include gasoline, diesel and jet fuel. However, furfural can also be transformed by hydrogenation, oxidation, decarboxylation and condensation reactions. The selective hydrogenation of furfural produces furfuryl alcohol, an important industrial compound, which is widely employed in the production of resins, fibers, and is considered an essential product for pharmaceutical applications. On the other hand, the oxidation of furfural produces furoic acid which is appliedin the agrochemical industry, where it is commonly transformed to furoyl chloride which is finally used in the production of drugs and insecticides. The oxidation and reduction of furfural can carry out through heterogeneous and homogeneous catalysis, and biocatalysis. Selectivity is an important issue in furfural hydrogenation and oxidation reactions since different products can be obtained by using monometallic or bimetallic catalysts and/or different catalyst supports. In biocatalysis approach, different enzymes, complete cells, tools of modern biotechnology, DNA sequencing, regulation of metabolic networks, overexpression of genes that encode enzymes of interest and optimization of the cellular properties of the microorganism are used. Herein, a review on the current status of furfuryl alcohol and furoic acid production from furfural by heterogeneous catalysis and biocatalysis has been studied. The stability, selectivity and activity of catalystsalong with the different furfural oxidation and reduction conditions have been pointed out. Additionally, the main enzymes, microorganisms and mechanism involved in the furfural degradation process have also been discussed.
