摘要：采用化学置换法制备了Pt/泡沫镍(foam-Ni)、Pd/foam-Ni、Pt-Pd/foam-Ni电极,采用线性伏安、交流阻抗、能谱仪(EDS)等技术研究了所制备的电极在6 mol/L的NaOH溶液中电催化性能。研究结果表明:所制备的电极在碱性溶液中都具有一定的电催化活性,但其电催化活性存在差异。在foam-Ni上沉积Pt、Pd制备的Pt/foam-Ni、Pd/foam-Ni和Pt-Pd/foam-Ni电极中,Pt-Pd/foam-Ni的电催化活性最好,充分说明二元催化剂的电催化性能要优于一元催化剂。
The Pt/foam-Ni,Pd/foam-Ni,Pt-Pd/foam-Ni electrodes were prepared by chemical replacement method.Catalytic activities of the prepared electrodes were studied by linear sweep voltammetry curves（LSV）,electrochemical impedance spectroscopy（EIS） and EDS techniques in 6 mol/L NaOH solution.The catalytic mechanism was analyzed.The experiment results show that all of these electrodes have catalytic activity in alkaline solution.However,they have differences in catalytic activity.Among the Pt/foam-Ni,Pd/foam-Ni and Pt-Pd/foam-Ni electrodes,which were prepared by depositing Pt and Pd on the foam-Ni,Pt-Pd/foam-Ni electrodes have the best catalytic activity.It illustrates the binary catalyst has better performance than the unitary catalyst.
