Method: The etching of the Ti sheet by using a mixed acid of H2SO4 and TA (volume ratio= 2: 1) for 50 min at 100 °C could produce a suitable interface for further modification. The morphologies, composition, and electrochemical properties of Yb doping on the electrode were characterized by SEM (Scanning Electron Microscopy), EDS (Energy-Dispersive Spectroscopy), Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS). The introduction of an appropriate intermediate layer, Zr-SnO2, was performed. We also tried to fabricate Ytterbium (Yb) doped Ti/Zr-SnO2/PbO2 electrodes by an electrodeposition method on the intermediate layer of Zr-SnO2. The surface morphology of the Ti/Zr-SnO2/PbO2 electrode was changed due to the Yb doping, which affected the electrocatalytic activity of the modified electrode. Result: The developed Yb-doped Ti/Zr-SnO2/PbO2 electrode showed improved removal efficiencies toward AYR. Conclusion: The effects of current density and initial AYR concentration on the electrochemical oxidation of AYR by Yb-doped Ti/Zr-SnO2/PbO2 were investigated. The removal rate of AYR was 97.3% in 180 min under the conditions of the current density of 60 mA/cm2 , initial AYR concentration of 50.0 mg L-1 , and Na2SO4 concentration of 0.10 mol L-1 .","PeriodicalId":10827,"journal":{"name":"Current Nanoscience","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140935454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Graphene Oxide is synthesized from graphite powder at room temperature. Hydrazine hydrate is used as a reducing agent to reduce the accumulated GO. Method: To understand the impact of reduction time on structural parameters of produced rGO, three different time limits, i.e. 4, 5, and 6 hrs at 800 °C are used. FTIR spectra show the presence of all functional groups to confirm the authenticity of rGO samples. The XRD peaks are utilized to calculate different structural parameters for all the samples to identify the effect of reduction time. A change in the band gap energy may be noticed from UV-Vis absorption spectra. Result: It indicates that with the increase in reduction time, the absorption edge shifts to a lower wavelength value. FESEM micrographs reveal a flake-like random growth of rGO with prominent wrinkled structures, which is a signature of graphene-like 2D material. Conclusion: Hence, from the structural and absorption studies, it can be concluded that an increase in reduction time will produce smaller rGO flakes in the Hummers synthesis method.","PeriodicalId":10827,"journal":{"name":"Current Nanoscience","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140935426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
