【摘要】：通過(guò)化學(xué)鍍技術(shù)制備了亞微米級(jí)的Ni-P鍍層石墨粉復(fù)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(duì)Ni-P-C復(fù)合粉體分別進(jìn)行表面形貌分析、表面成分分析和物相分析.通過(guò)對(duì)Ni-P-C材料電極進(jìn)行電解水析氫、循環(huán)伏安和Tafel極化等電化學(xué)測(cè)試,研究對(duì)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(xué)催化產(chǎn)氫性能.結(jié)果表明:利用化學(xué)鍍技術(shù)成功地在石墨粉體表面鍍上了一層亞微米級(jí)且均勻、致密的非晶態(tài)Ni-P合金.Ni-P-C(石墨)復(fù)合電極材料析氫能力強(qiáng),具有良好的電化學(xué)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.
