Abstract

Abstract : Suspension methods were used to synthesize surfactant-free Cu2 O quantum dots (Cu2 O-QDs) in high precursor concentrations using sodium hypophosphite as a reducing agent. Transmission electron microscopy (TEM) observations indicated that a large amount of Cu2 O-QDs were synthesized with diameters ranging from 7 to 10 nm. We propose a mechanism where DMSO acts as a surface passivation agent, explaining the possible formation of Cu2 O-QDs. Noticeably, the Cu2 O-QDs exhibited high and stable catalytic activity for the reduction of rhodamine B.
