Au-on-Pd bimetallic nanoparticles applied to the voltammetric determination and monitoring of 4-nitroaniline in environmental samples

Autor: Cristiane Luisa Jost, Carlos Eduardo Maduro de Campos, Welman C. Elias, Marília Reginato de Barros, João Paulo Winiarski

Publikováno v: Journal of Environmental Chemical Engineering. 9:105821

Palladium@Gold bimetallic nanoparticles (Au-on-PdNP) were synthesized and characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM). The nanomaterial was successfully applied in the modification of a glassy carbon electrode
