Electrolytic Oxidation of Lignin

Electrochemical oxidation of lignin at IrO2-based oxide electrodes

“…Electrochemical oxidation has been explored for the degradation of lignin [16][17][18][19][20]. The first effort toward an electrochemical oxidation of lignin was made by Bailey and Brooks in the mid1940s [21]. Complete degradation of butanol lignin at platinum in 1% NaOH was observed upon prolonged electrolysis.…”

Lignin‐Augmented Water Electrolysis

“…In another study, Chum and Osteryoung (10) have reviewed previous electrochemical work with lignin and other biomass material. tive oxidation of a butanol lignin in NaOH on a lead dioxide anode at a current density of 20 mA cm -2 resulted in degradation of lignin to low molecular weight compounds such as 2butanone, acetone, acetic acid, aromatic carboxylic acids, oxalic acid, and 2-hexanone (11). However, guidance will be gleaned from the summary of the work reported by Chum et al (9,10).…”

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

“…To our knowledge, the earliest electrochemical degradation of lignin represents the work by Bailey and Brooks; they studied the electrochemical oxidation and reduction of commercial sulfite waste liquor,a lkali lignin, and methylated butanol lignin to variousk etonesa nd acids using lead, cadmium, platinum, and mercury anodes. [76] Studies involving delignification, ECO, etcetera,f rom the 1940s to 80s have been reviewed in ab ook chapter by Chum et al [74] and will not be covered in detail here. Between the late 80'sa nd 2009, many studies were reported for the electrochemical degradation of lignin as at reatment methodf or industrial wastewater streamst hat contain lignin, [77][78][79][80] lignin-enhanced water electrolysis, [81] and hydrogen production.…”
