NiO and Co3O4 co-doped g-C3N4 nanocomposites with excellent photoelectrochemical properties under visible light for detection of tetrabromobisphenol-A

Abstract

Novel NiO/Co₃O₄/g-C₃N₄ nanocomposites with applications in photoelectrochemical sensing were designed and fabricated for the first time in this work. The morphology and microstructure of NiO/Co₃O₄/g-C₃N₄ were comprehensive investigated. The NiO/Co₃O₄/g-C₃N₄ nanocomposites exhibited higher photocurrent and donor density than those of pure g-C₃N₄, resulting in a higher photoelectrochemical activity for sensitive detection of TBBP-A in real water samples.
