We developed a CPM electrochemical sensor based on a composite of reduced graphene oxide (rGO) and silver nanoparticles (AgNPs) coated on a glassy carbon electrode (GCE). Sodium dodecyl sulfate (SDS) was used as a surfactant to prevent the aggregation of AgNPs. rGO and AgNPs were co-electrodeposited by cyclic voltammetry, varying the potential from -1.5 to 1.5 V vs. Ag/AgCl 3 M KCl. The electrochemical properties of the modified electrode were characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The rGO/AgNPs/GCE showed excellent electrocatalytic activity for the oxidation of CPM. The anodic peak potential, measured using CV, was 0.78 V vs. Ag/AgCl in a carbonate-bicarbonate buffer of pH 10. The modified electrode exhibited a linear response for CPM concentrations between 10 and 300 μM, with a limit of detection of 4.2 μM. Several potentially interfering species, including ionic and organic compounds, did not have any significant effect on the CPM determination.

In this study, we investigated the facile preparation of the titania-modified carbon paste electrode and the determination of trace amounts of hazardous Hg(II), Cu(II), and Pb(II) ions by applying the square wave anodic stripping voltammetry method. The titania nanoparticles were characterized using various techniques such as size analyzer, XRD, and FTIR to determine their chemical properties. The experimental findings demonstrated that the titania nanoparticles were uniformly distributed in the graphite used to construct the modified electrode and had an average particle size of 85 nm in crystalline anatase form. Compared with the measurement results, the prepared sensor exhibited excellent sensing performance against Hg(II), Cu(II), and Pb(II) ions with a low detection limit of 15.26, 0.56, and 1.65 nM, respectively. In ternary solutions, their simultaneous determinations showed that the electrode is more sensitive to Hg(II) and Pb(II) ions, with detection limits of 8.32 and 0.25 nM, respectively.

The studied Pd_xML/Pt(111) surfaces (<i>x</i> = 1, 2, 5, and 16 monolayers (ML)) are all more active than Pt(111) toward formic acid oxidation, even if the activity is very sensitive to the Pd film thickness and morphology. In sulfate solution, the competitive adsorption of long-range ordered (bi)sulfate on the pseudomorphic Pd terraces effectively hinders the formic acid oxidation only on the thinnest films. We could observe the different roles of the (bi)sulfate adsorption on the first and on the following deposited Pd layers. The sulfate adsorption competitive role rapidly fades away beyond about 5 ML of equivalent thickness, due to the surface roughness increasing and terraces width diminishing. In perchlorate media, anions do not adsorb competitively with formic acid intermediates, allowing a larger activity of the formic acid oxidation up to about 5 ML. At higher thicknesses, the difference in activity between the two electrolytic media is reduced, and it drops in both electrolytes close to 0.5 V vs. RHE, where Pd surface oxides are formed. Coupling the electrochemical results with the Pd layer structural description previously obtained from in situ SXRD experiments, the outstanding activity of Pd_1ML/Pt(111) observed in perchloric solution can be explained by the ligand effect of the underlying platinum atoms on the first pseudomorphic Pd layer. This advantageous effect is lost for Pd deposits thicker than 1 ML.</p><h3>Graphical Abstract</h3>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":535,"journal":{"name":"Electrocatalysis","volume":"14 4","pages":"561 - 569"},"PeriodicalIF":3.1,"publicationDate":"2023-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12678-023-00816-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4174076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
