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

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.
