“…Driven by the Principles of Green Chemistry, [8,[10][11][12] this Review focuses on electrocatalytic upgrading of lignin as a greener alternative to hydroprocessing and oxidative approaches for the followingr easons: i. Electrochemistry enables direct integration with renewable energy. [52,54] Unlike traditional reactions where activation energy is thermally supplied, electrochemistryo vercomes kinetic barriers with an applied potential. [54] Electrocatalytic reactions are thus generally performed at or near ambient temperature and pressure.…”

“…Water electrolysis is a well‐established method for hydrogen production. However, this process still suffers from high cost due to the expensive noble‐metal electrocatalysts needed and the high energy demands associated with the high potential needed for the OER . Among other organic molecules, such as methanol, ethanol, glycerol, 5‐HMF, or even whole biomass, lignin oxidation has been explored as a lower cost and lower energy alternative to water electrolysis to replace anodic oxidation while co‐generating hydrogen at lower potentials.…”

Greener Routes to Biomass Waste Valorization: Lignin Transformation Through Electrocatalysis for Renewable Chemicals and Fuels Production

Lignin valorization is essential for biorefineries to produce fuels and chemicals for a sustainable future. Today's biorefineries pursue profitable value propositions for cellulose and hemicellulose; however, lignin is typically used mainly for its thermal energy value. To enhance the profit potential for biorefineries, lignin valorization would be a necessary practice. Lignin valorization is greatly advantaged when biomass carbon is retained in the fuel and chemical products and when energy quality is enhanced by electrochemical upgrading. Though lignin upgrading and valorization are very desirable in principle, many barriers involved in lignin pretreatment, extraction, and depolymerization must be overcome to unlock its full potential. This Review addresses the electrochemical transformation of various lignins with the aim of gaining a better understanding of many of the barriers that currently exist in such technologies. These studies give insight into electrochemical lignin depolymerization and upgrading to value‐added commodities with the end goal of achieving a global low‐carbon circular economy.

“…[50][51][52] According to different needs, the furan ring and aldehyde group of furfural can be selectively upgraded to produce a variety of bio-based chemicals or bio-based fuels, such as furfuryl alcohol (FFA), tetrahydrofurfuryl alcohol (THFFA), cyclopentanone (CPO), 2methylfuran, tetrahydrofuran and γ-valerolactone (GVL) (Figure 1). [53][54][55] Because the furan ring and the aldehyde functional group are extremely active and will cause more by-products, therefore the selective hydrogenation of furfural is a major challenge. Currently, the main paths of upgrading furfural over MOFs derived catalysts include the aldehyde hydrogenation, furan ring hydrogenation and aldehyde dehydrogenation.…”

Metal organic framework (MOF) derived catalysts have been widely used in biomass platform compounds (BPC) hydrogenation field. This mini-review selectively introduces the research progress of MOFs derived catalysts in the upgrading of BPC. Particularly, MOFs derived catalysts prepared by pyrolysis and their catalytic applications for furfural and 5hydroxymethylfurfural are summarized in this mini-review. In addition, the factors affecting the performance of MOFs derived catalysts prepared by pyrolysis are discussed briefly and then the potential improvement studies on MOFs derived catalysts prepared by pyrolysis for upgrading of BPC are also put forward. We deem that this mini-review will provide valuable insights into the design and application of MOFs derived catalysts prepared by pyrolysis for upgrading of BPC to biobased chemicals.

“…[6][7][8][9][10] Notably, electrochemistry allows to convert green electricity, derived from wind and solar energy, directly into useful chemicals, and kinetic barriers are overcome by applying a suitable potential over the electrodes. Hence, no additional reagents are required to enable reduction [11][12][13][14] and oxidation processes, [15] which can aid to further reduce fossil fuel consumption (e. g., hydrogen is often derived from natural gas via the water-gas shift reaction). [16] While several useful electrochemical strategies for the conversion of furfural have been developed, the focus so far was almost exclusively on the optimization of a single electrode reaction.…”

A Divergent Paired Electrochemical Process for the Conversion of Furfural Using a Divided‐Cell Flow Microreactor

et al. 2020

Furfural is a prominent, non‐petroleum‐based chemical feedstock material, derived from abundantly available hemicellulose. Hence, its derivatization into other useful biobased chemicals is a subject of high interest in contemporary academic and industrial research activities. While most strategies to convert furfural require energy‐intensive reaction routes, the use of electrochemical activation allows to provide a sustainable and green alternative. Herein, a disparate approach for the conversion of furfural is reported based on a divergent paired electrochemical conversion, enabling the simultaneous production of 2(5 H )‐furanone via an anodic oxidation, and the generation of furfuryl alcohol and/or hydrofuroin via a cathodic reduction. Using water as solvent and NaBr as supporting electrolyte and electron‐mediator, a green and sustainable process was developed, which maximizes productive use of electricity and minimizes byproduct formation.
