Extensive utilization of synthetic dyes in various industries poses a
great threat to the environment. These dyes are toxic in nature and
cause serious health problems in the living beings. The presence of
these dyes in water also affects the photosynthetic activity of aquatic
plants as they interfere with the incoming sun rays and gas dissolution.
Although different methodologies have been adopted to treat the dye
contaminated water but still many improvements have to be done. Metal
oxide nanofibers present a better alternative in waste water treatment
which are able to degrade the organic dyes using advanced oxidation
processes. Herein, we have fabricated nickel oxide nanofibers using cost
effective electrospinning technique with excellent photocatalytic
activity in the presence of visible light to completely mineralize the
highly recalcitrant diazo congo red dye. Development of such nanofibers
for the degradation of highly stable dyes may act as a major component
of nano-remediation processes in the near future.
