【摘要】：通过化学镀技术制备了亚微米级的Ni-P镀层石墨粉复合粉体新材料(即Ni-PC).采用扫描电子显微镜、X-射线能谱仪、X-射线粉末衍射仪对Ni-P-C复合粉体分别进行表面形貌分析、表面成分分析和物相分析.通过对Ni-P-C材料电极进行电解水析氢、循环伏安和Tafel极化等电化学测试,研究对比了Ni-P-C(石墨)材料与试剂石墨粉体以及纯Ni电极的电化学催化产氢性能.结果表明:利用化学镀技术成功地在石墨粉体表面镀上了一层亚微米级且均匀、致密的非晶态Ni-P合金.Ni-P-C(石墨)复合电极材料析氢能力强,具有良好的电化学活性.
[Abstract]:A new sub-micron Ni-P coated graphite powder composite powder (Ni-PC) was prepared by electroless plating. The surface morphology of Ni-P-C composite powder was analyzed by scanning electron microscope (SEM) and X-ray powder diffraction (X- ray powder diffractometer). Surface composition analysis and phase analysis. Electrochemical measurements of hydrogen evolution, cyclic voltammetry and Tafel polarization of Ni-P-C electrode were carried out. The electrochemical catalytic hydrogen production properties of Ni-P-C (graphite) materials, reagent graphite powder and pure Ni electrode were compared. The results showed that a layer of submicron was successfully deposited on the surface of graphite powder by electroless plating. The dense amorphous Ni-P alloy. Ni-P-C (graphite) composite electrode has strong hydrogen evolution ability and good electrochemical activity.
