Studies on Structure and Electrocatalytic Hydrogen Evolution of Nanocrystyalline Ni—Mo

摘要 NanocrystallineNi-Mo-Fealloydepositswereobtainedbyelectrodeposition.ThestructuresofthealloydepositswereanalyzedbyX-raydiffraction(XRD)andX-rayphotoelectronspectroscopy(XPS).TheXRDresultsofnanocrystallineNi-Mo-Fealloydepositshowthatmanydiffractionlinesdisappear,andthatthereisonlyonediffractionpeakat44.0°.TheXPSresultsofnanocrystallineNi-Mo-Fealloydepositsindicatethatthenickel,molybdenumandironofthedepositsexistinmetallicstate,andthatthebindingenergyofthealloyedelementsincreasestosomeextent.ThenanocrystallineNi-Mo-FealloydepositelectrodemayofferbetterelectrocatalyticactivitythanthepolycrystallinenickeleletrodeandthenanocrystallineNi-Moalloyelectrode.TheelectrochemicalimpedancespectrafromthenanocrystallineNi-Mo-Fealloyelectrodeindicatethathydrogenevolutionin30%(m/m)KOHatloweroverpotentialisinaccordancewiththeVolmer-Tafelmechanism,butwiththeVolmer-Heyrovskymechanismathigheroverpotential.
