通过一步电沉积法制备CP@Pb电极，并将其用于催化顺丁烯二酸（C₄H₄O₄）电还原反应合成丁二酸（C₄H₆O₄）。利用SEM、TEM、XRD等手段对CP@Pb电极表面结构、物相组成等进行表征，通过CV及CP等方法研究CP@Pb电极在酸性环境中对C₄H₄O₄的电还原催化行为。结果表明，CP@Pb电极对C₄H₄O₄电还原具有良好的催化性能；反应温度为318.15 K时，在0.25 mol/L H₂SO₄+0.30 mol/L C₄H₄O₄中还原电流密度达到191.3 mA/cm²（-1 V）；当还原电流密度为120 mA/cm²时，合成丁二酸的纯度为96%。

CP@Pb electrode is prepared through a one-step electrodeposition method and used to catalyze the electroreduction reaction of maleic acid (C₄H₄O₄) to synthesize succinic acid (C₄H₆O₄).The surface structure and phase composition of the as-prepared CP@Pb electrode are analyzed by scanning electron microscope (SEM), transmission electron microscope (TEM) and X-Ray diffractometer (XRD).The cyclic voltammetry (CV) and chronopotentiometry (CP) are employed to study the electroreduction catalytic behavior of C₄H₄O₄ on CP@Pb in an acidic environment.The results show that the CP@Pb electrode has good catalytic performance for the electroreduction of C₄H₄O₄.The reduction current density of CP@Pb in 0.25 mol·L^-1 H₂SO₄+0.30 mol·L^-1 C₄H₄O₄ reaches 191.3 mA·cm^-2 at a reaction temperature of 318.15 K.The synthesized C₄H₆O₄ has a purity of 96% when the reduction current density is 120 mA·cm^-2.
