摘      要：An S-scheme heterojunction photocatalyst is capable of boosting photogenerated carrier separation and transfer,thus maintaining high photooxidation and photoredox ***,a 0D Ag_(3)PO_(4) nanoparticles(NPs)/1D TiO_(2) nanofibers(NFs)S-scheme heterojunction with intimate interfacial contact was designed via the the hydro-thermal *** from the abundant hydroxyl groups and size confinement effect of TiO_(2) NFs,the average diameter of the Ag_(3)PO_(4) nanoparticles decreased from 100 to 22 nm,which favored the construction of a 0D/1D geometry *** multifunctional Ag_(3)PO_(4)/TiO_(2) sample exhibited excellent photocatalytic activity and stability in photocatalytic oxygen production(726μmol/g/h)and photocatalytic degradation of various organic contaminants such as rhodamine B(100%),phenol(60%)and tetracycline hydrochloride(100%).The significant improvements in the photocatalytic performance and stability can be attributed to the intimate interfacial contacts and rich active sites of 0D/1D geometry,fast charge carrier migration,and outstanding photoredox properties induced by the S-scheme charge-transfer *** work offers a promising strategy for constructing 0D/1D S-scheme heterojunction photocatalysts for improved photocatalytic performance.
