“…Notably, this system achieves high SPCE (80.2%) with high formate selectivity (83.8%) and Faradaic efficiency (FE) (89.6%) at flow rate of 1.98 mL min −1 and current of 3 A (Supplementary Figs. 20 , 21 ), outpacing that in batch reactor (formate selectivity of 30.4%) and previous literature (formate selectivity <55%) 61 , 62 . The effectiveness of the SPCFR system was then corroborated by selective conversion of other biomass-derived polyhydroxy compounds into formate, which cannot be accomplished in a batch reactor (Fig.…”

Electrooxidation of biomass platforms provides a sustainable route to produce valuable oxygenates, but the practical implementation is hampered by the severe carbon loss stemming from inherent instability of substrates and/or intermediates in alkaline electrolyte, especially under high concentration. Herein, based on the understanding of non-Faradaic degradation, we develop a single-pass continuous flow reactor (SPCFR) system with high ratio of electrode-area/electrolyte-volume, short duration time of substrates in the reactor, and separate feeding of substrate and alkaline solution, thus largely suppressing non-Faradaic degradation. By constructing a nine-stacked-modules SPCFR system, we achieve electrooxidation of glucose-to-formate and 5-hydroxymethylfurfural (HMF)-to-2,5-furandicarboxylic acid (FDCA) with high single-pass conversion efficiency (SPCE; 81.8% and 95.8%, respectively) and high selectivity (formate: 76.5%, FDCA: 96.9%) at high concentrations (formate: 562.8 mM, FDCA: 556.9 mM). Furthermore, we demonstrate continuous and kilogram-scale electrosynthesis of potassium diformate (0.7 kg) from wood and soybean oil, and FDCA (1.17 kg) from HMF. This work highlights the importance of understanding and suppressing non-Faradaic degradation, providing opportunities for scalable biomass upgrading using electrochemical technology.

Sustainable Productions of Organic Acids and Their Derivatives from Biomass via Selective Oxidative Cleavage of C–C Bond

et al. 2018

Biomass is renewable and the most abundant carbon resource, and it shows great potential for sustainable production of chemicals in the future. With respect to limited fossil reserves, biomass conversion has aroused global attention. The use of biomass as a resource has developed rapidly in recent years, and various kinds of chemicals could be produced from biomass. Although biomass is annually renewable and abundant, it is important to process it in the most efficient way. Before rushing into biomass conversion, it is necessary to consider what chemicals are reasonably and economically produced from biomass. In this Review, we first analyzed the products from biomass based on the structural properties and economics. Taking into account the oxygen-rich character of the feedstock, it is a reasonable route to convert the biomass into valuable oxygen-containing fine chemicals, among which organic acids are one class of important and widely used fine chemicals. Then, we provided insights into the recent progress in the oxidative cleavage of biomass into organic acids and their derivatives, such as esters and anhydrides. The biomass resources cover the lignocellulose biomass, sugars, chitin, platform molecules, and fats. As biomass resources are generally polymers and the C–C bond is the backbone, the oxidative cleavage of C–C bond can break up the biomass to small molecules and introduce acid functionality at the same time. This Review particularly focuses on the generation of acids via a C–C bond-oxidative-cleavage process. Various methods, catalytic systems, and C–C bond-cleavage mechanisms are summarized. Finally, we conclude with mentioning the challenges in the oxidative conversion of biomass and the possible research direction in this area.

“…Formic acid (FA) has been studied as a promising candidate for fuel cell applications because of its facile oxidation kinetics, high theoretical cell potential, and low fuel crossover . In addition, formic acid can be prepared by synthesis from biomass, − recycling carbon dioxide by catalytic hydrogenation, − or electrochemical reduction. − Biobased FA is a safe reagent for energy storage and chemical synthesis, and its production is economically appealing …”

Iridium-Catalyzed Continuous Hydrogen Generation from Formic Acid and Its Subsequent Utilization in a Fuel Cell: Toward a Carbon Neutral Chemical Energy Storage

et al. 2016

This study represents a notable step toward a potentially carbon neutral energy storage solution based on formic acid as a hydrogen/ energy carrier. A catalytic system derived from IrCl 3 and 1,3-bis(2′-pyridylimino)-isoindoline (IndH) in the presence of aqueous sodium formate showed high selectivity and robustness for hydrogen generation from formic acid (FA) at 90−100 °C under both high and moderate pressure conditions suppressing the formation of CO impurity. Being a solid substance, the catalyst can be recovered by a simple filtration, if necessary. Furthermore, addition of neat formic acid is sufficient to reuse the catalyst and maintain a constant flow of H 2 and CO 2 mixture and the stable performance of a coupled fuel cell. The easy to recycle catalyst did not show any loss of activity after 20 days of continuous use, and similar activity was observed even a year after the original preparation. The reactor for formic acid decomposition provided a one to one ratio of a H 2 /CO 2 mixture that was coupled to a hydrogen/air proton exchange membrane (PEM) fuel cell to demonstrate a stable and continuous conversion of chemical energy to electricity. This integrated system embodies the first example of an indirect formic acid fuel cell, which can function, without the requirement of applying inert conditions and feed gas purification, for extended periods of time.
