▎ 摘　　要

In this letter, a reduced graphene oxide/CuI (rGO/CuI) nanocomposite was obatined by a facile chemical reduction route for the first time. The different reaction conditions that affected the catalytic properties of rGO/CuI nanocomposite were investigated. The catalytic activity of rGO/CuI nanocomposite for the N-phenylation of indole was much better than that of rGO and CuI.
