Abstract: A new type of nitrogen &surflur co-doped graphene aregeol with high electrocatalytic performance for oxygen reduction reaction was successfully synthesized via the hydrothermal treatment of graphene oxide and ammonium thiocyanate mixture dispersion for the ammonium thiocyanate decomposing into NH3,H2 S and C2 S at 170℃.A subsequent thermal treatment at 1000℃ under N2 atmosphere was carried out.The NSG-P showed a promising electrocatalytic performance which ORR peak was at-0.36 Vand electron transfer number was about 3.8.The excellent properties of the sample can be attributed to the three dimensional cross-linking structure and N&S co-doped into the graphene framwork.
