Substituting the sluggish water oxidation with biomass oxidizable species such as lignin at anode is thermodynamically more favorable, enabling energy efficient hydrogen production and concomitant fine chemicals. The present study shows the organosolv lignin electrooxidation in an additively manufactured 3D printed reactor (3DPR) consisting of platinized nickel foam (PtNF) as anode and cathode and compared with commercial hardware electrolyzer (CHE). The electrolysis of organosolv lignin in 3DPR outperformed CHE by achieving 1.23 times higher current at an applied voltage range from 0 to 2.2 ​V with a membrane (Nafion 115) interposed between anode and cathode under a continuous flow of lignin feed at the anode. The chronoamperometry study reveals a mixture of diverse aromatic compounds, including vanillic acid, syringic acid, 3,5-dimethoxy-4-hydroxyacetophenone, 2-hydroxyacetophenone, 4-ethycathecol, and 2,6-dimethoxyphenol in anolyte, and sinapic acid and vanillin acetate in catholyte.

Herein, multi-interface carbon-coated FeCoNi nanoneedles grown on carbon cloth (FeCoNi@C/CC) were synthesized by a combination of hydrothermal process and chemical vapor deposition (CVD) technology with the concept of “green synthesis”.

Here the departure diameter of hydrogen bubbles and oxygen bubbles and their detachment process from a nickel wire electrode during water electrolysis are studied using high-speed photography. The results show that in industrial alkaline environment, the departure diameters of most hydrogen bubbles and oxygen bubbles are generally smaller than 60 ​μm and 250 ​μm with the current density ranges from 0.15 to 0.35 ​A/cm<sup>2</sup>. The adhesion force of hydrogen bubbles on a nickel wire is found to be so weak that they can separate with a tiny size. The diameters of oxygen bubbles conform to normal distribution, and its distribution range widens with the increase of current density. The theoretical analysis show that the comprehensive conversion rate of current-to-bubble is unexpectedly low especially at low current densities, which may be attributed to the loss of gas components caused by bubble detachment mode. The majority of oxygen bubbles detach by a sudden bounce after coalescence, which may bring strong disturbance to the concentration boundary layer. This also indicates the coalescence-induced bubble departure mode may occupy a dominant position in the electrolyzers.</p></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"5 ","pages":"Article 100052"},"PeriodicalIF":0.0,"publicationDate":"2024-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949881324000180/pdfft?md5=29e09bb4a4ffb0f43ae2d97b3b7ceac7&pid=1-s2.0-S2949881324000180-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141485433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
