Conclusions• Galvanic exchange between Ag nanoparticles and Au3+ ionscan be carried out on RGO sheet in a controlled way.• RGO is capable of anchoring both semiconductor and metalnanoparticles.• Photocatalysis experiments of MV2+ reduction showmediation of metal nanoparticles and RGO in electron transfer.
