The treatment of graphene oxide (GO) with potassium thioacetate followed by an aqueous work-up yields a new material via the ring-opening of the epoxide groups. The new material is a thiol-functionalized GO (GO-SH) which is able to undergo further functionalization. Reaction with butyl bromide gives another new material, GO-SBu, which shows significantly enhanced thermal stability compared to both GO and GO-SH. The thiol-functionalized GO material showed a high affinity for gold, as demonstrated by the selective deposition of a high density of gold nanoparticles.
将氧化石墨烯（GO）与硫代乙酰胺处理，然后进行水性处理，通过开环环氧基团生成一种新材料。这种新材料是一种巯基功能化的氧化石墨烯（GO-SH），它可以进一步进行功能化。与正丁基溴反应得到另一种新材料 GO-SBu，与 GO 和 GO-SH 相比，它显示出显著增强的热稳定性。如通过选择性沉积高密度的金纳米粒子所证明的，这种巯基功能化的氧化石墨烯材料对金具有高亲和力。
