One-pot electrochemical synthesis of graphene by the exfoliation of graphite powder in sodium dodecyl sulfate and its decoration with platinum nanoparticles for methanol oxidation

摘要: Abstract We demonstrate a method which directly grows large areas of graphene on carbon paper and glassy (GC) substrates from graphite powder anionic surfactant, sodium dodecyl sulfate, assisted electrochemical exfoliation. The electrochemically reduced has been carefully characterized by scanning electron microscopy (SEM) techniques. Particularly, SEM images show enhanced growth structures formed ‘urchin’ objects. CV spectra illustrate that variety the oxygen-containing functional groups thoroughly removed plane via reduction. Potential peak (Ep) electrode in [Fe(CN) 6 ] 3−/4− solution is as small 212 mV 168 mV smaller than electrode. This could be attributed to high quality accelerating transfer rate electrochemistry. Finally, platinum was electro onto GC modified based electrodes for use methanol oxidation. catalytic activities graphene-supported Pt nanoparticles Pt-GC electrocatalysts oxidation were 1900 915.5 A g −1 Pt, can reveal particular properties exfoliated supports.
