【摘要】：通過化學鍍技術制備了亞微米級的Ni-P鍍層石墨粉復合粉體新材料(即Ni-PC).采用掃描電子顯微鏡、X-射線能譜儀、X-射線粉末衍射儀對Ni-P-C復合粉體分別進行表面形貌分析、表面成分分析和物相分析.通過對Ni-P-C材料電極進行電解水析氫、循環(huán)伏安和Tafel極化等電化學測試,研究對比了Ni-P-C(石墨)材料與試劑石墨粉體以及純Ni電極的電化學催化產氫性能.結果表明:利用化學鍍技術成功地在石墨粉體表面鍍上了一層亞微米級且均勻、致密的非晶態(tài)Ni-P合金.Ni-P-C(石墨)復合電極材料析氫能力強,具有良好的電化學活性.
[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.
