Area of Science:

Nanotechnology
Green Chemistry
Environmental Science

Background:

Silver nanoparticles (AgNPs) have diverse applications but conventional synthesis methods raise environmental concerns.
Mercury (Hg²⁺) contamination in water poses significant environmental and health risks.
Developing sustainable and sensitive methods for Hg²⁺ detection and environmental remediation is crucial.

Purpose of the Study:

To report the green synthesis of biogenic AgNPs using phytochemicals.
To evaluate the synthesized AgNPs for dual applications: mercury ion sensing and catalysis.
To demonstrate a sustainable alternative for AgNP production and environmental applications.

Main Methods:

Green synthesis of AgNPs using plant extracts.

Characterization using UV-vis, FTIR, EDX, TGA, DLS, XRD, SEM, and TEM.

Evaluation of AgNPs for Hg²⁺ detection and catalytic degradation of pollutants.

Main Results:

Green synthesis confirmed by visual color change and SPR band at 441 nm.
Characterization confirmed spherical AgNPs (20 nm) with a face-centered cubic structure.
High sensitivity for Hg²⁺ detection (LOD 14 ppm) and significant catalytic activity observed.

Conclusions:

The study successfully synthesized biogenic AgNPs via a green route.
The AgNPs demonstrated excellent performance in Hg²⁺ sensing and catalytic applications.
This approach provides a sustainable and efficient method for AgNP production and environmental remediation.
