Preparation of Ag‐Al₂O₃ nano structures by combustion method and investigation of photocatalytic activity
Source abstract
Abstract
Abstract In this research, Ag‐Al 2 O 3 nanostructures have been prepared via combustion synthesis and ammonium acetate and urea have been applied as fuels. The prepared Ag‐Al 2 O 3 nanostructures were characterized by DTA, XRD, SEM, TEM, and BET spectroscopy. The effect of different ratios of silver to alumina and fuel percentage on morphology and particle size of prepared products were investigated. The results showed that using ammonium acetate fuel led to the production of Ag‐γ‐Al 2 O 3 nanocompounds, while using urea produced Ag‐α‐Al 2 O 3 . Also, the photocatalytic activity of Ag‐Al 2 O 3 nanostructures for Congo red degradation was evaluated by UV‐Vis diffuse reflectance spectroscopy. The photocatalytic activity of Ag‐Al 2 O 3 was examined under UV‐Vis irradiation and showed significant photocatalytic efficiency.
