Novel CuBi2O4/CuS composite photocatalysts with different mass ratios 1%, 5%, 10% of CuBi2O4 have been synthesized by the solid-phase method and precipitation-deposition method. The physical and photophysical properties of the photocatalyst have been characterized by XRD, SEM, EDX, BET- surface area, UV-visible diffuse reflection spectra, photoluminescence spectra and Antibacterial activity. The prepared photocatalytic material of 10% CuBi2O4/CuS exhibited higher photocatalytic performance as well as excellent degradation of 4-Amino phenol (4-Ap) compared to the rest and the individual component. The results of PL indicated that CuBi2O4 and CuS could combine well to form a composite structure which facilitated electron-hole separation, and increasing photocatalytic activity. On the basis of the experimental results and estimated energy band positions, the mechanism of enhanced photocatalytic activity was proposed.
