Effective utilization of CO2 into valuable green fuels and its sensing is focused research area. Aiming above, this work is focused on fabrication of electrochemical coupled sensing system for degradation of 4-nitrophenol to CO2 from wastewater samples, electrochemical reducing system for transforming CO2 to alcohols and selective amperometric sensing system for quantifying alcohols. A graphene anchored iron oxide electrode was used as an electrocatalyst to facilitate the electrochemical oxidation process to mineralized organic pollutants into water and CO2. The CuO film on silicon substrate was used in cathodic compartment for converting CO2 to methanol and ethanol. Alcohol oxidase modified Au–Cu nanoparticle modified pencil graphite was selective sensing and quantifying the methanol and ethanol. The experimental results revealed that, graphene anchored iron oxide showed maximum degeneration of 4-nitrophenol 72% at 0.9 V. Furthermore, simultaneous reduction of CO2 at cathode gave good yield of the liquid fuels CH3OH and C2H5OH were 105.0 and 90.0 μmol/L respectively. In addition, Alcohol oxidase modified Au–Cu nanoparticles modified pencil graphite biosensor displays a linear response to both methanol and ethanol in the range 0.250–850 μmol/L with a detection limit of 0.07 μmol/L (S/N = 3) (RSD = 0.004 μA) and 0.7–800 μmol/L with detection limit of 0.068 μmol/L (S/N = 3) (RSD = 0.005 μA) with >40% quantitative yield. The response time is less than 50 s at ambient conditions. Consequently, the ethanol and methanol yield were obtained 30.0%. Our developed three-in-one provides a convenient, simple and reliable method to remediate polluted water and utilizing CO2 into green fuels.","PeriodicalId":760,"journal":{"name":"Russian Journal of Electrochemistry","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139476113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hierarchical porous carbon material (KACM) was prepared via high-temperature calcination and KOH activation using azalea (a species of rhododendron) biomass as the carbon source. KACM and thionine (Thi) were simultaneously assembled on a glassy carbon electrode (GCE) to construct a porous carbon/thionine ratiometric electrochemical biosensor for the detection of ascorbic acid and uric acid. Electrochemical evaluation showed that the Thi/KACM/GCE has good electrochemical performance, strong catalytic activity toward AA and UA oxidation, and good separation of the two oxidation peaks. Under the optimized conditions, Thi/KACM/GCE has a wide linear range (0.05–9 mM) and low detection limit (6.4 μM for AA and 10 μM for UA). Additionally, the biosensor exhibited good selectivity, stability, and reproducibility. Thi/KACM/GCE was used for the simultaneous detection of AA and UA in human urine with 99.4–101.0% recovery of the compounds. This study reports for the first time the use of azaleas in electrochemical biosensors, and the results show that small changes in the structural properties of biomass materials can affect their electrochemical properties.","PeriodicalId":760,"journal":{"name":"Russian Journal of Electrochemistry","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139476165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, naphthols are toxic to environment and human health. So it is very important to simultaneously detect them, will make contributions to both the manufacture and the environment management. Herein we developed a simple, cost effective, electrochemical sensor based on magnetite (Fe3O4 nanoparticles) porous reduced graphene oxide/carbon nanotubes (Fe3O4@prGO-CNT) nanocomposite for simultaneous detection of 1-naphthol and 2-naphthol. Voltammetric responses suggest dramatical improvement of electrocatalytic properties of naphthols by incorporating Fe3O4@prGO-CNT on carbon paste electrode (CPE). Differential pulse voltammetric (DPV) measurement depicts large potential separation of about 200 mV between naphthols, allows their simultaneous determination from binary mixture. Under optimized condition, Fe3O4@prGO-CNT/CPE manifested linear relationships of 1-naphthol and 2-naphthol in the range of 0.5–30 and 0.7–40 μM with detection limit (S/N = 3) of 76 and 82 nM respectively. Moreover, Fe3O4@prGO-CNT/CPE showed satisfactory response towards wastewaters and river waters for determining 1-naphthol and 2-naphthol concentrations.","PeriodicalId":760,"journal":{"name":"Russian Journal of Electrochemistry","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139476036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
