Photocatalytic Degradation Of Indigo Carmine And Phenol Using Agzs04-Deposited Zno Under Outdoor Light Irradiation
Silver sulfate (Ag2S04) was successfully deposited on ZnO via a simple impregnation method. The as-synthesized sample was characterized by XRD, SEM, TEM, EDX, FTIR, UV-vis DRS and BET surface characteristic. Then, the photocatalytic activities of pure ZnO and three Ag2S04-deposited ZnO with diffe...

| Summary: | Silver sulfate (Ag2S04) was successfully deposited on ZnO via a simple
impregnation method. The as-synthesized sample was characterized by XRD, SEM,
TEM, EDX, FTIR, UV-vis DRS and BET surface characteristic. Then, the
photocatalytic activities of pure ZnO and three Ag2S04-deposited ZnO with different
Ag2S04 loading were being evaluated for the degradation of indigo carmine and
phenol under outdoor light irradiation. Results showed that the photocatalytic
activities of all theer Ag2S04-deposited ZnO were higher than pure ZnO and
commercial Ti02 for both pollutants degradation, especially 0.03 Ag2S04/ZnO which
exhibited superior photocatalytic performance compare to others. After that,
calcination temperature at 300 oe was found to be the most suitable condition for the
preparation of 0.03 Ag2S0 |
