Abstract

Constructing a specific nanocomposite film with a large surface area and excellent electrocatalytic activity is important for its application as an electrochemical sensor. In this study, for the first time, an ultrahigh performance composite film based on a heteropolyanion PW9V3O403− (abbreviated as WV) decorated by Pt@Pd alloy nanoparticles (Pt@Pd NPs) and Prussian blue nanoparticles (PB NPs) was illustrated via a layer-by-layer self-assembly approach. The composition, morphologies, and nanostructures characteristics of the [PB/WV–Pt@Pd]6 composite film were completely studied by scanning electron microscopy (SEM), atomic force microscopy (AFM), UV-vis spectroscopy, FT-IR spectra, and X-ray photoelectron spectroscopy (XPS), respectively. The special irregular morphology of the [PB/WV–Pt@Pd]6 composite film provides a high specific surface area to boost the electrochemical activity, while the larger roughness and strong electronic cloud facilitate H2O2's fast reduction at pretty low potential. Under optimum conditions, the [PB/WV–Pt@Pd]6 composite film-based sensor presented a broad linear scope of 4.00 × 10−7 M to 2.65 × 10−3 M and a low detection limit of 1.00 × 10−7 M (S/N = 3). Thus, with seeming stability, anti-interference performance, and selectivity, the suggested sensor could be conceivably utilized to detect H2O2 in actual samples.
