Preparation of Ag‐Al₂O₃ nano structures by combustion method and investigation of photocatalytic activity

Abstract

In this research, Ag‐Al2O3 nanostructures have been prepared via combustion synthesis and ammonium acetate and urea have been applied as fuels. The prepared Ag‐Al2O3 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‐Al2O3 nanocompounds, while using urea produced Ag‐α‐Al2O3. Also, the photocatalytic activity of Ag‐Al2O3 nanostructures for Congo red degradation was evaluated by UV‐Vis diffuse reflectance spectroscopy. The photocatalytic activity of Ag‐Al2O3 was examined under UV‐Vis irradiation and showed significant photocatalytic efficiency.

Nanocomposite with high adsorption activity developed using stabilized silver modified alumina and TiO2-NPs incorporated into β-cyclodextrin-graphene oxide

“…As previously reported, Ag/Al 2 O 3 nanocomposite was synthesized using solution combustion and urea as fuel [ 19 ]. The silver-promoted materials were prepared by dissolving an appropriate amount of AgNO 3 (1.56 gr) and Al(NO 3 ) 3 .9H 2 O (7.36 gr) in DI water and using urea (3.49 gr) as a combustion fuel.…”

“…We have simultaneously produced alumina and silver nanoparticles using the solution combustion synthesis (SCS) process, which is a simple, rapid, and versatile method for producing various nanoscale materials [ 18 , 19 ].…”

The effects of titanium dioxide (TiO2) nanoparticles on physiological, biochemical, and antioxidant properties of Vitex plant (Vitex agnus - Castus L)

“…With the rapid development of nanotechnology, engineered nanomaterials have also found an extensive usage in production of industrial, commercial, medical, diagnostic, and agricultural products [ [1] , [2] , [3] , [4] , [5] , [6] , [7] ]. Today, many industries use large quantities of nanoparticles, which enter the environment and the bodies of humans and animals in large quantities [ [8] , [9] , [10] , [11] ].…”
