In this study, silver nanoparticles were synthesized using leaves of the herbal plant Kalanchoe pinnata, showing antibacterial activity against E. coli and photocatalytic activity in dye degradation. The physicochemical parameters, absorption spectra, crystalline nature, stability, and morphology of AgNPs were examined to understand their properties.
Silver nanoparticles (AgNPs) were synthesized via green synthesis using a new herbal plant Kalanchoe pinnata (known as life plant) leaves. Effects of physicochemical parameters like temperature, pH and concentration on AgNPs were examined, and the absorption spectra were observed due to strong surface plasmon resonance. The crystalline nature and stability of AgNPs were confirmed by XRD pattern and zeta potential, respectively. The morphology of AgNPs was studied using FESEM and HRTEM. AgNPs showed antibacterial activity against the gram-negative E. Coli bacteria and photocatalytic activity in the degradation of rhodamine B dye with a reaction rate constant of 0.042 min-1.
