Abstract
Hierarchical porous flower-like spinel nickel cobaltite (NiCo2O4) nanoflakes was synthesized by using simple and economical chemical method. The structure, morphology and optical properties of synthesizes nanoflakes were analyzed by using XRD, FE-SEM and UV?visible. The NiCo2O4 nanoflakes showed 96% degradation of TBO in 50 min and after 10 cycles of operation, the photocatalytic activity was enough for the 89% degradation of TBO under natural sun light. When compared with other photocatalysts materials, porous NiCo2O4nanoflakes showed excellent thermal and chemical stability and offer exceptional electron transfer rate during photocatalytic reactions for real environmental pollution cleanup applications. The efficient photocatalytic efficiency and stability of NiCo2O4 nanoflakes is attributed to its inimitable structure with large surface area along with maximum active sites. This augments the efficiency of harvesting sun light, and spread active species over surface to decrease e-/ h+ pair recombination. On the whole, this work demonstrates that the synthesis of nanoflower NiCo2O4 can be used as potential candidate to remove organic pollutant and infections from water under natural sun light irradiations for industrial applications.
