Abstract
The photoelectrochemical properties of FTO/TiO/AIS nanoheterostructures containing Ag-In-S (AIS) nanoparticles (NPs) produced by the size-selective precipitation were investigated. It was found that the photocurrent of such composites increases by almost twice with decrease of the average AIS NP size from 3.5-4 to ~2 nm. The dependence of the rate constant of photoinduced electron transfer between AIS NPs and TiO on the average size of the NPs is similar in nature and agrees with the size dependence of the photoelectrochemical activity of TiO/AIS nanoheterostructures.
