N2 - An efficient photocatalytic composite Ni/ZnO/g-C3N4 (NiZG), has been successfully synthesized by coupling graphitic carbon nitride (g-C3N4) with nickel doped zinc oxide nanoparticles (Ni/ZnO NPs) via a cost-effective chemical co-precipitation method. This fabricated composite (NiZG) was meticulously characterized by FTIR, XRD, TEM, UV–vis spectroscopy, BET surface area, and transient photocurrent response. The catalytic efficiency of the (NiZG) composites was assessed by measuring the UV–vis absorption spectra of methylene blue and the bactericidal efficiency was checked against Gram-positive and Gram-negative microbes. The NiZG-70 composite (containing 3% Ni/ZnO and 70 % g-C3N4) demonstrated superior bactericidal and photocatalytic properties under solar radiations compared with Ni/ZnO, g-C3N4 alone. Photoluminescence analysis revealed that the electron-hole recombination in the composite was sufficiently reduced because of the Ni atoms functioning as electron transmitters at the interfaces. The recycling measurement of the composite signifies the extra stability of the NiZG and makes it a practical candidate for environmental remediation applications.
