A carbon (Vulcan XC-72R) supported PdSn catalyst was prepared via polyol method and its surface electronic and chemical properties were investigated by advanced surface analytical techniques such as scanning electron microscopy (SEM), X-ray diffraction spectroscopy (XRD), X-ray Photoelectron Spectroscopy (XPS), temperature-programmed reduction with H-2 (TPR-H-2) and transmission electron microscopy (TEM). Electrochemical measurements were performed by employing cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques on PdSn/GCE/Vulcan XC-72R electrode. The developed sensor showed a wide linear range up to 10 mM with a 0.77 mu M low limit of detection (LOD) as well as high stability. Further experiments were performed on food samples containing BA to achieve real sample measurements. For real sample measurements, PdSn/GCE/Vulcan XC-72R electrode was used for the determination of BA in different kinds of samples such as mayonnaise, ketchup and carbonated beverages.eninfo:eu-repo/semantics/closedAccessPdSnElectrocatalysisBenzoic AcidFood SafetyArticle316Q2Q211181124WOS:000474252600016
