dc.description.abstractInfront of the emerging interest and talent to search for new materials, we have synthesized Nickel oxide (NiO) nanoparticles decorated Zinc oxide (ZnO) nanorods composite (NiO/ZnO) nanostructure. By the X-ray powder diffraction and high-resolution transmission electron microscopy (HRTEM) the NiO/ZnO heterostructure formation was confirmed. The fabricated environmental affable NiO/ZnO composite nanostructure under UV-lights shows a well-defined photoreduction characteristic of hexavalent Chromium (Cr) (VI) to tri-valent Chromium (Cr) (III). Photoluminescence (PL) spectroscopy, photocurrent study, and electrochemical impedance spectroscopy, proved that the superior photoreduction property is ascribed due to the decreased electron-hole recombination process. In addition to the photocatalytic activity rate of the NiO decorated ZnO nanorods was much higher than that of exposed ZnO nanorods dfv for the reduction of chromium (VI) and their rate of activity is found to be 0.306 min?1 . All results have demonstrates that in the development of highperformance photocatalyst the suitable surface engineering may open up new opportunities.en_US
