Preparation and Characterization of Ni-Modified Graphene Oxide Complex as an Efficient Catalyst for the Synthesis of Sulfides via Reaction of Arylhalides with S8 or Thiourea

In this work, complex of Ni-modified graphene oxide was prepared and characterized using FT-IR spectroscopy, SEM, XRD, TGA and ICP-OES techniques. This compound used as an efficient and recoverable catalyst for the C-S coupling reaction using sulfur-transfer reagents (S-8 or thiourea). The catalyst was easily separated using a simple filtration and reusable without significant loss of their catalytic efficiency.
