Nickel Oxide Decorated Zinc Oxide Composite Nanorods: Excellent Catalyst for Photoreduction of Hexavalent Chromium March 2018 Journal of Colloid and Interface Science DOI: 10.1016/j.jcis.2018.03.012 Project: Metal-semiconductor heterostructure for photocatalytic application Simranjeet Singh Imtiaz Ahmed Krishna Kanta Haldar Abstact In light of the growing interest and ability to search for new materials, we have synthesized Nickel oxide (NiO) nanoparticles decorated Zinc (ZnO) nanorods composite (NiO/ZnO) nanostructure. The NiO/ZnO heterostructure formation was confirmed by X-ray powder diffraction and high-resolution transmission electron microscopy (HRTEM). The fabricated environmental friendly NiO/ZnO composite nanostructure shows a well-defined photoreduction characteristic of hexavalent Chromium (Cr) (VI) to tri-valent Chromium (Cr) (III) under UV-light. Such an enhanced photoreduction property is attributed due to the decreased electron-hole recombination...
