Insight into the growth mechanism of AgIn5S8 nanoparticles in a low temperature co-precipitation process and their visible-light-driven photocatalytic activities

AgIn5S8 (AIS) nanoparticles with excellent photocatalytic performance were synthesized by a convenient low temperature co-precipitation process. The growth mechanism of AIS in the reaction system was studied in terms of reaction time, which had obvious effect on the composition, morphology, and photoelectrochemical properties of the resulting samples. During the co-precipitation process, the initially formed Ag2S precipitate gradually...
