Graphitic Carbon Nitride as a Platform for the Synthesis of Silver Nanoclusters

Abstract Graphitic carbon nitride (CN) synthetized by the thermal polycondensation of melamine at 550 °C for 4 h was further exfoliated by heating at 500 °C for 3 h. Silver cations were adsorbed on the exfoliated graphitic carbon nitride (CNE) and then reduced by sodium borohydride forming silver na...

The Ag NCs were able to collect the photoinduced electrons of CNE and thus reduce their recombination with the holes.
