Abstract
A facile/clean/sustainable route for the preparation of silver nanoparticles (Ag NPs) was investigated using Trigonella foenum-graecum (TF) leaf extract. The bio-reduced Ag NPs showed photocatalytic degradation potential of 88% and 86% for reactive blue 19 (RB19) and reactive yellow 186 (RY186), respectively (at 180 min). The complete mineralization of degraded medium was monitored by decline in chemical oxygen demand (COD). The role of activation energy in photocatalytic degradation process was investigated across different temperatures. In light of their photocatalytic efficiency, reusability, and environment friendly synthesis approach, biogenic Ag NPs were demonstrated as effective system for efficient water purification.
