| In this paper, Ag/ZnO/HZSM-5ternary nanocomposites with different Ag loadings were prepared by the photo precipitation
method. The prepared photocatalysts were characterized by XRD, BET, SEM and TEM. The photocatalytic activity
of ZnO/HZSM-5 for 4-nitrophenol (4-NP) degradation was increased by silver doping. Effects of various parameters such as the
initial concentration of 4-NP, pH and Ag loading on 4-NP degradation were studied. The best activities were obtained for the
3% Ag-10% ZnO/HZSM-5 nanocatalysts at pH 7.9, 1 g L−1 of the catalyst and 5 ppm of 4-NP. Langmuir–Hinshelwood (L–H)
model was proposed for the rate equation of the 4-NP degradation. |
