摘　　要：选用Dawson型多酸K6[P2W18O62]·14H2O (P2W18)和Pt-Ni合金纳米粒子作为电化学活性组分,制备了P2W18/Pt-Ni合金纳米粒子复合膜电极,采用循环伏安法研究了复合膜电极的电化学行为。实验结果表明,P2W18/Pt-Ni合金纳米粒子复合膜电极具有良好的重复性和稳定性,并展现出较P2W18电极更好的对H2O2的电催化活性。The Dawson-type polyoxometalate(K6[P2W18 O62]·14H2O(P2 W18))and Pt-Ni alloy nanoparticles was used as electrochemical active components,and the P2 W18/Pt-Ni alloy nanocomposite film electrodes wasfabricated.The electrochemical behavior of the electrodes was studied by cyclicvoltammetry.Experimental results showed that the P2W18/Pt-Ni alloy nanocomposite film electrode has good repeatability and stability,and exhibited better electrocatalytic activity for H2O2 than the P2W18electrode.
