Abstract: (1575 Views)
Titania- metal nanoparticle composite aerogel simultaneously benefits from unique morphological characteristics of aerogel, intrinsic properties of titania and plasmonic effects of metal nanoparticles. Therefore these nanocomposites are one of the best candidates in plasmonic photocatalystic applications. In this research by loading titania aerogel via immersion method with gold nanoparticles and gold and silver nanoparticles (simultaneous existence) two different nanocomposites were synthesized and their photocatalystic activity was investigated through photodegradation of salicylic acid (test molecule) by means of UV-Vis spectroscopy. The obtained results showed that the presence of Au increases the photocatalystic efficiency of titania aerogel and furthermore the simultaneous existence of Au & Ag also improves the activity of the nanocomposite.
