I am trying to dope sulphur into Graphite Oxide and P123 using various amounts of Na2S.9H2O followed with hydrothermal washing and calcining.
When I run EDS on the samples, there seems to be no sulphur at all, what would be the problem? Or does anyone know how I could improve my experimental procedure, please?
Cheers
Many hetero-atoms like (P, N, B, F, S, O), but the S or F atom is not easy to dope with GO, you must change the raw materials-precursor., doping depends on Sulphur precursor and raw source mass ratio in some literature reported.
Hydrothermal method is very good one for Sulphur doping carbon (Graphene, CNTs, Activated carbon), to increase the Raw (Sulfur) source of precursor.
some reference,
1. Phys. Chem. Chem. Phys., 2016,18, 1125-1130 - graphene oxide (GO) sheets and sodium sulphide (Na2S) as precursors through a hydrothermal reaction process at 200 °C in one pot.
