The photocatalytic rate of ZnO supported onto natural zeolite nanoparticles in the photodegradation of an aromatic amine

Aniline and its derivate are critical environmental pollutants, thus, the introduction of an eco-friendly catalyst for removing them is important research future. The ZnO supported on ball-mill prepared clinoptilolite nanoparticles (CNPs) was via ion-exchange process followed by calcination process. amount loaded in ZnO-CNP (CZ) samples varied as 0.54, 0.63, 0.72, 0.86 meq/g Zn(II) concentration solution from 0.1 to 0.5 M. briefly characterized XRD, FTIR, DRS techniques. pHpzc value various ZnO-CNPs about 7.1 that had no change with loading. By applying Scherrer equation XRD results, a nano-dimension 50 nm obtained catalyst. Bandgap energy estimated Kubelka-Munk reflectance spectra. CZ2 3.64 eV. sample then used photodegradation 2,4-dichloroaniline (DCA). Raw zeolite showed relatively low photocatalytic activity. degradation efficiency recording absorbance DCA UV-Vis spectrophotometer. effects essential operating factors were kinetically studied Hinshelwood results. 2 w% best rate optimal conditions 0.75 g/L, CDCA: 15 ppm, initial pH: 5.8. Finally, HPLC analysis blank photodegraded solutions at 180 300 min confirmed 74 87% molecules degraded during these times. results confirm onto caused enhanced activity because internal electrical field prevents e?/h+ recombination.
