“…reported the researches abut obtaining vanillin with a high selectivity by a combined approach of electrochemistry and product isolation by adsorption. In addition, electrocatalytic hydrogenation (ECH) has been proved to be one of the most attractive methods for the hydrogenation of all kinds of unsaturated molecules, including aromatic compounds, so ECH also has potential application in the degradation of lignin.

Electrochemical degradation of bamboo lignin through electrocatalytic redox between Cu cathode and Pb/PbO 2 anode in sodium hydroxide solution was investigated in this work. Electrocatalytic performance of the electrode system was analyzed by cyclic voltammetry and cathodic polarization to validate that Cu and Pb/PbO 2 electrodes had a great ability of electrochemical oxidation and electrocatalytic hydrogenation (ECH) in lignin alkali solution. Through the electrocatalytic redox in the process, 24 kinds of products were detected by gas chromatography-mass spectrometry (GC-MS) and three of them (vanillin, syringaldehyde and p-coumaric acid) were detected with high yields by gas chromatograph (GC) with internal standard method. Effects of operating parameters, i. e., lignin concentration, current density and temperature, were also investigated to find the optimum degradation conditions at which the maximum yields of vanillin, syringaldehyde and pcoumaric acid could be obtained.

“…For conversions higher than 80 %, Ni/C featured the highest selectivity towards ECH (86–89 %). As reported in literature, nickel is also selective for the electrocatalytic hydrogenolysis of benzyl ethers in the form of Raney nickel, and the ECH of furfural . While large variations in ECH/HDO selectivities as a function of conversion percentage is not particularly advantageous, it is worth noting that the Ni/C catalyst shows the lowest loss in ECH selectivity over the entire range of conversions.…”

Electrocatalytic Hydrogenation of Oxygenates using Earth‐Abundant Transition‐Metal Nanoparticles under Mild Conditions

Electrocatalytic hydrogenation (ECH) is a sustainable pathway for the synthesis of value-added organic compounds, provided affordable catalysts with high activity, selectivity and durability are developed. Here, we synthesize Cu/C, Ni/C, and CuNi/C nanoparticles and compare their performance to Pt/C, Ru/C, PtRu/C for the ECH of hydroxyacetone, a bio-derived feedstock surrogate containing a carbonyl and a hydroxyl functional group. The non-precious metal electrocatalysts show promising conversion-time behavior, product selectivities, and Faradaic efficiencies. Ni/C forms propylene glycol with a selectivity of 89 % (at 80 % conversion), while Cu/C catalyzes ECH (52 % selectivity) and hydrodeoxygenation (HDO, 48 % selectivity, accounting for evaporation). CuNi/C shows increased turnover frequencies but reduced ECH selectivity (80 % at 80 % conversion) as compared to the Ni/C catalyst. Importantly, stability studies show that the non-precious metal catalysts do not leach at operating conditions.

“…The nitrogen content reflects the protein residues in bamboo lignin . According to the electrocatalytic hydrogenation mechanism, the source of hydrogen and the production of m ‐DEB, PX, OX, and other hydrogenation products in the electrocatalytic hydrocracking of bamboo lignin could be reasonably explained by Eqs. (1)–(6).…”

This study proposed a novel procedure for the selective production of 1,3-diethylbenzene (m-DEB) by the electrocatalytic hydrocracking of bamboo lignin in alkaline solution. The electrocatalytic reaction was carried out in the fixed bed threedimensional electrode reactor, which consisted of Ti/SnO 2 -Sb 2 O 3 /α-PbO 2 /β-PbO 2 anode, copper mesh cathode, and ceramic particles that filled between the anode and cathode. Under the optimal conditions of 50 g/L lignin in NaOH solution (0.5 mol/L), a current density of 25 mA/cm 2 , a temperature of 25°C, and reaction time of 10 h, bamboo lignin was completely decomposed and an accumulated total yield of 35.7 g/L was obtained. Furthermore, the accumulated yield of m-DEB reached a maximum of 0.361 g/g-lignin by using a lignin concentration of 30 g/L. In addition, the formation of m-DEB was a zero-order kinetic reaction.
