Abstract

The development of innovative technology for effective pollutant degradation is becoming more important as a result of major environmental issues. Here, ZnO nanoparticles were synthesized using facile and aqueous chemical growth routes. Analytical techniques such as scanning electron micrographs (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Zeta Seizer (ZS), and Zeta Potential were used to analyze the resultant nanoparticles (ZP). The ZnO reveals a nanocluster texture that has a medium scale of 27 nm and a surface charge (17 ± 3 mV) with a wurtzite phase and crystalline nature. Photo catalysts have a higher potential for the thermal disposal of chlorophenols pollutants due to their low cost and simple synthesis procedure. The as-prepared sample underwent photocatalysis for the simultaneous photo-degradation of PCP and TCP as a model dye under sunlight. The ZnO nanostructure exhibited an exceptional degradation of around 85–90% for PCP and TCP in the aqua liquid, with the lowest amount of catalyst dosage of 240–250 μg individually and simultaneously, over 3 min beneath the sun ray. The greater productivity of the ZnO nanostructure for natural deterioration during solar irradiation indicates that the aqueous chemical growth enables the creation of effective and affordable photocatalysts for the photodegradation of a variety of environmental contaminants.
