摘要: Abstract Graphene oxide (GO) wrapped Ag 3 PO 4 sub-microparticles were prepared by in situ deposition–precipitation method. By hybridization of with GO nanosheets, a 6-fold enhancement the photodegradation rate toward orange methyl (MO) under visible light irradiation ( λ ≥ 420 nm) was observed compared pure sub-microsparticles. The hybrid photocatalysts also exhibited excellent stability successive MO degradation experiments. highly enhanced photocatalytic activity and mainly attributed to quick transfer photogenerated electrons from which could effectively suppress electron–hole pairs recombination thus inhibit photocorrosion . These high-efficient stable expected show considerable potential applications wastewater treatment water splitting.
