Synthesis of Multimetal-Graphene Composite By Mechanical Milling

Abstract

Multimetal-graphene composites were synthesized using the ball milling technique. To prepare the composite, graphite powder was mixed with Fe, Cr, Co, Cu and Mg powders. This mixture was then mechanically milled for 35 h in toluene medium. After milling, the multimetal- graphite mixture was mixed with sodiumlauryl sulfate and sonicated for 2 h. Sonication led to the exfoliation of graphene sheets.
