This paper reports the effect of different concentrations of Rosa ‘Andeli’ double delight petals aqueous extract (PERA) in the synthesis of silver nanoparticles (Ag-NPs), using an easy green chemistry method. Its kinetics study and photocatalytic activity were also evaluated. The Ag-NPs were obtained using an aqueous silver nitrate solution (AgNO3) with 9.66% w/v, 7.25% w/v, and 4.20% w/v PERA as both reducing–stabilizing agent. The formation of the Ag-NPs was demonstrated by analysis of UV–vis spectroscopy, scanning electron microscopy–energy dispersive spectroscopy (SEM–EDS) and transmission electron microscopy (TEM). TEM analysis shows spherical nanoparticles in shape and size between ∼0.5 and 1.4 nm.
A comparative study was done to determine which concentration was the best reducing–stabilizing agent, and we found out that “ultra-small” nanoparticles (0.5–1.1 nm) were obtained with 9.66% w/v of PERA. The size of the Ag-NPs depends on the concentration of PERA and Ag(I).
The reaction of formation of “ultra-small” Ag-NPs, proved to be first order for metallic precursor (silver) and second order for reducing–stabilizing agent (PERA).
The Ag-NPs showed photocatalytic activity, in degradation of commercial dye with an efficiency of 95%.
