主 题:plasma activation hydrogen peroxide nanocarbon defect oxygen functional groups
摘 要:Oxidized nanocarbons(ONCs)have been regarded as efficient electrocatalysts for H2O2 ***,wet chemical procedures involving large volumes of strong acid and long synthetic time are usually needed to obtain these ***,a plasma activation strategy is developed as a rapid and environmentally benign approach to obtain various ONCs,including oxidized multiwalled carbon nanotubes,single-walled carbon nanotube,graphene,and super P carbon *** a few minutes of plasma activation,oxygen-containing functional groups and defects can be effectively introduced onto the surface of *** electrocatalytic activity and selectivity are demonstrated by the plasma-ONCs for H2O2 *** oxidized multiwalled carbon nanotubes as an example,high selectivity(up to 95%)and activity(0.75 V at 1 mA cm^(−2))can be achieved in alkaline ***,ex situ x-ray photoelectron spectroscopy and in situ Raman measurements reveal that C–O,C=O,edge defect,and sp2 basal planar defect are probably the active sites.
