Hydrothermal synthesis of Ag/rGO@CTFE nanocomposite as a promising photocatalyst for degradation action

The present study reports a green synthesized via eco-friendly hydrothermal treatment of silver-reduced graphene oxide (Ag/rGO) nanocomposite using chamomile tea flowers extract (CTFE). Initially, the synthesis of Ag/rGO@CTFE nanocomposite was confirmed by the formation of greyish black color. The synthesized Ag/rGO@CTFE nanocomposite was characterized by Raman spectroscopy, XRD, FE-SEM with EDS, HR-TEM and FTIR analyses. Spherical shape of the synthesized Ag/rGO@CTFE nanocomposite with varied sizes of 55-60 nm was observed by HE-TEM analysis. Face centered cubic crystalline structure of synthesized Ag/rGO@CTFE nanocomposite was confirmed by XRD analysis. In addition, Ag/rGO@CTFE nanocomposite exhibited 97% of Rhodamine B (Rh B) and 87% of Evans blue (EB) dye degradation activity under visible light irradiation. Ag/rGO@CTFE nanocomposite exhibited notable photo-catalytic activity in carcinogenic organic dyes. Hence, it's a first reports on hydrothermal treatment of Ag/rGO@CTFE nanocomposite using CTFE for photo-catalytic application. (C) 2020 Elsevier B.V. All rights reserved.
