Oxidized few layer graphene and graphite as metal-free catalysts for aqueous sulfide oxidation

Few layer graphene and natural graphite were chemically modified by oxidation with HNO sub(3) at 80 and 140 degree C and used to promote the oxidation of sulfide ions in aqueous solutions. TEM, potentiometric titration, XRD, BET and Raman spectroscopy show that HNO sub(3) treatment even at 140 degre...
