CaIn₂S₄–In₂O₃hybrid nanofibers with expedited photocarrier separation for fast photocatalytic bacterial inactivation under visible light

Abstract

Semiconductor heterostructures are of critical importance in steering the flow of photocarriers (i.e. e- and h+). Here, we have fabricated heterostructure-based semiconductor fibers comprising electrospun In2O3 nanofibers coaxially wrapped by...

Construction of a novel S-scheme AgVO3/CaIn2S4 heterostructure for efficient photodegradation of tetracycline hydrochloride

“…3d shows two peaks at 162.28 eV and 161.08 eV, representing S 2p 1/2 and S 2p 3/2 , confirming the presence of S 2− ions in the sample. 38 It is interesting to note that the binding energies of the In 3d and S 2p peaks in the AC-0.025 composite are slightly shifted towards a higher value with respect to blank CaIn 2 S 4 , while the binding energies of Ag 3d move towards lower binding energies with respect to blank AgVO 3 . This observation indicates the spontaneous transfer of electrons from CaIn 2 S 4 to AgVO 3 upon composite formation.…”
