Improving visible-light active photocatalytic performance of the heterostructured g-C3N4-V-TiO2 (g-C3N4-Vanadium-TiO2) hybrid catalyst has been synthesized via facile calcination and ultrasonicdispersion facilitated hydrothermal techniques were considered. The phase composition, morphology,surface area, chemical structure as well as optical properties were systematically characterized. HR-TEMimages were exposed good crystallinity of g-C3N4-10% V-TiO2 nanocomposite (size~35–40 nm) with VTiO2porous discrete on g-C3N4 nanosheets. Too occurred in high pore volume and large surface area(91.5 m2 g 1) of g-C3N4-10% V-TiO2 hybrid catalyst compared than pristine g-C3N4. The 10% g-C3N4-V-TiO2photocatalyst shows substantial photocatalytic activity, 5.7 and 4.8 times higher that pristine g-C3N4nanosheets and TiO2 under visible light with the degradation efficiency over 99.5% for 60 min. Besides,the recycling test specified that the g-C3N4-10% V-TiO2 photocatalyst had admirable stability up to 5sequential cycles. The trapping assessments which authorize that OH radicals and h+ plays an activerole in the degradation process and the separation of photoinduced charges transversely theheterostructure boundary reserved electron-hole recombination they were good agree with PL studies. Moreover, g-C3N4-10% V-TiO2 composite catalyst show high catalytic antibacterial activity againstEscherichia coli (G ) and the Staphylococcus aureus (G+) bacteria.
