    摘要:

    采用脈沖電鍍技術(shù)獲得了高活性Ni-Mo-W析氫合金陰極。以析氫反應(yīng)過(guò)電位為考察指標(biāo)，確定了脈沖鍍Ni-Mo-W合金的最佳電鍍條件，如Na2WO4·2H2O濃度、平均電流密度和占空比等。同時(shí)，系統(tǒng)研究了Mo和W含量對(duì)Ni-Mo-W合金鍍層成分和組成的影響規(guī)律。結(jié)果表明，在二元合金中添加W能有效提高電極的析氫反應(yīng)活性 (η200=80 mV)；非晶態(tài)Ni-Mo-W合金的組織結(jié)構(gòu)主要取決于Mo含量；與非晶態(tài)Ni-Mo合金鍍層相比，Ni-Mo-W合金析氫陰極的電化學(xué)穩(wěn)定性得到一定程度的提高。

    Abstract:

    The amorphous Ni-Mo-W alloy coating with high HER (hydrogen evolution reaction) activity was obtained by pulse plating. In view of HER overpotential, the optimum electrodeposition conditions to prepare Ni-Mo-W coating in pulse plating process were determined, e.g. Na2WO4·2H2O concentration, average current density and duty cycle. Correspondingly, the effects of molybdenum and the tungsten contents on the compositions and the components of Ni-Mo-W coatings were investigated systematically. The results show that adding tungsten into Ni-Mo binary alloy coating could increase the HER activity effectively (h200 = 80 mV) and the amorphous microstructure of Ni-Mo-W coating mainly depends on the molybdenum content. After long-term electrolysis, compared with amorphous Ni-Mo coating, the electrochemical stability of amorphous Ni-Mo-W coating is improved to some extent due to the poor dissolution of molybdenum and tungsten.
