dc.description.abstract | Integrating green nanotechnology
contributes to a circular economy by converting waste
into functional materials, thereby reducing pollution
and promoting the sustainable use of resources. This
study centers on the synthesis of zinc oxide
nanoparticles (ZnO NPs) derived from Banana
Flower (Musa acuminate) (BF), emphasizing their
photocatalytic efficiency against IC 50 orange
pigment dye (PD), a widely used industrial dye. The
optimal conditions for synthesizing ZnO NPs with
improved yields were determined by varying
parameters such as pH, ion precursor concentration,
plant extract-to-ion solution ratio, irradiation
methods, and incubation time. The NPs were
characterized using UV-Vis spectroscopy, FTIR,
SEM, TEM, EDS, and XRD analysis. Surface plasmon
resonance peaks between 350 and 370 nm
preliminarily confirmed the formation of ZnO NPs.
FTIR analysis indicated the stretching mode of the Zn
O bond around 625 cm-1. SEM analysis revealed the
spherical morphology of the NPs, while TEM analysis
showed an average particle size of 84.3 nm. XRD
analysis confirmed the presence of the hexagonal
crystalline structure typical of ZnO NPs, and EDS
analysis validated the elemental composition, with Zn
and O being the predominant constituents. Under
optimized conditions, including catalytic load, pH,
and dye concentration, the ZnO NPs synthesized from
BF demonstrated exceptional photodegradation
efficiency, achieving a 93.80% dye degradation
within 7 hours. These findings highlight the potential
of ZnO NPs synthesized with BF as a sustainable
solution for textile and wastewater treatment
applications due to their high photodegradation
efficiency, environmentally friendly synthesis process,
and effective removal of industrial dyes. | en_US |
