Özet:

 

In the present study, ZnO nanostructures were synthesized and immobilized on   the surface of diatomite via a simple sonochemical method for the   photocatalytic degradation of formaldehyde in the aqueous phase. The   characterization of as-prepared ZnO/diatomite nanocomposite was carried out   by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), and   Fourier transform infrared spectroscopy (FT-IR). The photocatalysis of   formaldehyde was favored at neutral pH. At a ZnO to diatomite ratio of 0.3,   increasing the photocatalyst dosage from 0.2 to 1.5 g/L resulted in   increasing the photocatalytic removal of formaldehyde from 37.51% to   88.05%. At a formaldehyde concentration of 100 mg/L, the complete removal   of formaldehyde was attained within the reaction time of 50 min. A   mineralization efficiency of 53% was achieved, thereby confirming a   suitable mineralization of formaldehyde within the short reaction time of 60   min.
