Study On Electrodeposition Ni-Mo-P Alloy In The Stabilized Magnetic Field And Their Activity As Cathodes For Hydrogen Evolution

Electrolyzing water to make hydrogen is the most effective method.However,the iron and Raney-Ni electrode of the electrolytic technique used nowadays result in high energy consumption due to the high hydrogen evolution reaction (HER) potential.So,it is an important research subject on reducing the energy consumption and developing efficient electrolysis of catalytic activity of hydrogen evolution electrode materials.A new method for plating film is put on electroplating with electromagnetic filed.In this paper,the effects of electromagnetic filed on electroplating Ni-Mo-P alloy and hydrogen evolution electricity catalytic performance were studied.Ni-Mo-P alloy that has many advantages which is dense, coating hardness,binding force strong,corrosion resistance and so on has the broad application prospect.At present, study about electrodeposition hydrogen evolution cathode materials alloy in the stabilized magnetic field is less.So study on hydrogen evolution cathode materials have theoretical and realistic significance.In this paper,the effects of electromangnetic field(of0～1.0T magnetic flux density)in electroplating Ni-Mo-P alloy on pure bronze and steel were studied.The field include surface quality, alloy composition, structure, hydrogen evolution electricity catalytic performance and microscopic structure.The rule of the effect on performance indexes of Ni-Mo-P alloy were obtained by analyzing the experiment data.From the results, it was shown that:comparing to the deposits without magnetic field;the deposits in magnetic field becomes more homogeneous and more smooth; but the content of Mo increases, the deposition of Ni is inhibited, and the content of P remains basically unchanged; the catalytic properties of hydrogen evolution increases.
