摘要

To synthesize metallic and metal oxide nanoparticles using biological systems, green synthesis of nanoparticles has emerged as an important area as a sustainable approach compared to conventional chemical/physical methods. Structural activity relationship studies (SARS) that examine the correlation between the structure of a nanoparticle and its catalytic properties have also been discussed. The current article summarizes recent developments in green nanoparticle synthesis with a particular emphasis on nanocatalysis basics. The influence of temperature, pH, concentration of metal precursor, reaction time, and characterization of AgNPs by TEM, SEM, XRD, and UV–Vis spectroscopy was systematically addressed. Furthermore, various applications of the synthesized AgNPs as catalysts in green conditions were also explored in multiple sectors, including waste remediation, green synthesis, biomedicine, agriculture, textiles, and energy production. This systematic investigation clearly illustrates the promising impact of phytogenic nanotechnology in environmentally-friendly chemistry and material production.
