Facile one-pot green synthesis of Aloe vera mediated silver nanoparticles and their catalytic efficiency towards organic transformations

Abstract

A facile approach for the synthesis of Aloe vera mediated silver nano-particles (AgNPs) has been carried out via chemical route. The developed Aloe vera mediated AgNPs were characterized by using various techniques such as SEM, FT-IR etc. Additionally, catalytic applications of this interesting nanomaterial were utilized for the synthesis of 4-phenylthiazole- 2-amine and its derivatives. After completion of catalytic reactions, Aloe vera mediated AgNPs were easily recycled without any significant loss in catalytic activity. The robust features of the current approach involve an outstanding catalytic performance, ease of catalyst retrievability, easy work up procedure, and large substrate tolerance. Besides this, the green chemistry metrics for the products formed such as E-factor (Environment Factor), PMI (Process Mass Intensity), RME (Reaction Mass Efficiency), Atom Economy (AE) and carbon efficiency (CE) were in associated with high efficiency and selectivity which further confirms the effectiveness of this approach. This work highlights the significance of using economic and eco-friendly approach for synthesizing thiazole derivatives in good to excellent yields via Aloe vera mediated AgNPs under waste free conditions.
