Abstract: A recoverable graphene-supported nanocatalyst, a process for its preparation, and its use in catalysing organic reactions are disclosed. The nanocatalyst comprises catalytically active metal nanoparticles, such as nanoparticles of palladium, platinum, gold, copper, or nickel, anchored upon a graphene-based support, such as graphene oxide or reduced graphene oxide, through interaction with oxygen-containing surface functional groups of the support. The nanoparticles are formed by associating a metal precursor with the surface functional groups and reducing it, so that the nanoparticles nucleate and anchor at the functional-group sites and are uniformly dispersed over the support. The firm anchoring suppresses leaching of the metal and sintering of the nanoparticles, so that the nanocatalyst combines the high activity of dispersed metal nanoparticles with ready recoverability and durable reusability. The nanocatalyst is separated from a reaction mixture by filtration, centrifugation, or, when a magnetic component is incorporated, by a magnet, and is reused over many cycles with retention of activity and low metal leaching, which retains the valuable metal and avoids contamination of the product, for use in cross-couplings, hydrogenations, oxidations, and reductions.
