通过在滤纸表面依次负载石墨层、聚苯胺（PANI）层和铂（Pt）纳米颗粒，制备了滤纸/石墨-聚苯胺@铂（F/G-PANI@Pt）电极。利用SEM、TEM、XRD和FT-IR等手段对所制备电极表面形貌、结构组成进行表征。并用CV和CA等电化学方法研究了所制备电极在H₂SO₄介质中对H₂O₂电还原的催化行为。结果表明，F/G-PANI@Pt电极在酸性环境中具有良好的稳定性，对H₂O₂的电还原具有优越的电催化活性。其优良的电化学活性归因于特殊的三维（3D）结构以及PANI和Pt之间的协同作用。

Filter paper/graphite-polyaniline@Pt (F/G-PANI@Pt) electrode is prepared through loading in turn graphite layer,polyaniline (PANI) layer and platinum (Pt) nanoparticles on the surface of filter paper.Scanning electron microscopy (SEM),transmission electron microscopy (TEM),X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) are employed to characterize the surface morphology,structure and composition of the prepared electrode.The electrochemical behavior of the prepared electrode for the electro-reduction of H₂O₂ in H₂SO₄ medium is studied by means of cyclic voltammetry (CV) and chronoamperometry (CA) methods.It is indicated that F/G-PANI@Pt electrode has good stability in an acidic environment and a high electrocatalytic activity for the electroreduction of H₂O₂.Its excellent electrocatalytic activity is attributed to the special three-dimensional (3D) structure and the synergistic effect between PANI and Pt.
