在这项研究中，我们提出了一种在氢氧化钠溶液中通过 Cu/NieMoeCo 阴极和 Pb/PbO2 阳极之间的电化学氧化还原从玉米秸秆木质素生产可再生化学品的有效方法。通过循环伏安测试和极化曲线研究了Pb/PbO2阳极的电化学氧化性能和Cu/NieMoeCo在木质素碱溶液中的电催化加氢性能。采用傅里叶变换红外光谱（FTIR）和高效液相色谱（HPLC）对木质素残渣的官能团和分子量分布进行表征。通过GC-MS分析，证实碱玉米秸秆木质素降解产物中有24种化合物。除此之外，还观察到一些具有商业价值的化学物质，包括反式阿魏酸、香草醛、3-羟基-4-甲氧基苯基乙酮、丁香醛、乙酰丁香酮和4-甲氧基-3-甲基苯酚
In this study, we put forward an effective method of producing renewable chemicals from corn stover.lignin with electrochemical redox between the Cu/NieMoeCo cathode and Pb/PbO2 anode in sodium.hydroxide solution. Cyclic voltammetry tests and polarization curves were conducted to research the.electrochemical oxidation performance of Pb/PbO2 anode and electrocatalytic hydrogenation of Cu/.NieMoeCo in lignin alkali solution. Fourier transform infrared spectroscopy (FTIR) and high performance.liquid chromatography (HPLC) were used to characterize the functional groups and molecular weight.distribution of the lignin residue. By GC-MS analysis, it confirmed that there were 24 kinds of compounds.in degradation products of alkali corn stover lignin. In addition to this, some commercial value chemicals.including trans-ferulic acid, vanillin, 3-hydroxy-4-methoxyphenyl-ethanone, syringaldehyde, acetosyringone and 4-methoxy-3-methyl-phenol were also observed
