Photochemical Synthesis of Cu2O and Cu2O/Ag Nanoparticles in Polyols

Resumo

Cu₂O nanoparticles were synthesized by photoreduction of copper(II) complex compounds with ethylene glycol and glycerin in the photolite volume. Their optical properties, morphology, phase composition, and photocatalytic activity in methyl orange decomposition were studied. The electrochemical substitution reaction afforded Cu₂O/Ag composite nanoparticles. Their increased activity in photodegradation reactions of methyl orange in comparison with unmodified Cu₂O particles was found.
