Abstract
In the experiments of electrochemical exfoliated graphene, the insert voltage1~3V and electrolyte composition of 2.4g sulfuric acid, 0 ~5 mL of 30% KOH and 100 mL of deionized water should were changed to find their relationship with graphene defects. Analysis of Raman spectra illustrated that using a lower insert voltage and a OH-: H+ ratio for the electrolyte of 1:2 reduced the number of defects. Its defect ratio ID/IG was 0.5.
