Green Synthesis of Electrochemically Active Silver Nanoparticles

The manufacturing of silver nanoparticles (AgNPs) is now safer, more economical, nontoxic, and environmentally benign thanks to the extraction of Cirsium japonicum. The extracts from C. japonicum worked as a stabiliser and reducer. AgNP synthesis was verified by UV/Vis spectroscopy. There have been studies done on the production of AgNP at various temperatures and concentrations. Their dispersion was validated by high resolution transmission electron microscopy (HRTEM), which also revealed their tiny (2-8nm) spherical form, lack of aggregation, and spherical shape. AgNPs were found to be crystalline using X-ray diffraction (XRD). Using EDX, it was possible to determine the substance's elemental makeup. FTIR spectroscopy was used to identify the chemical molecules that coat AgNPs. The photodegradation of bromo phenyl blue has been investigated in a variety of settings, including experimental setups and catalyst size and structure. In about 12 min, 98 percent of the bromo phenyl blue was destroyed using AgNPs as photo catalysts. Water purification and the transformation of organic hazardous substances into non-hazardous products are obvious uses for AgNPs due to their powerful reductive capabilities. Amazing electro-catalytic abilities for hydroquinone were shown by the electrode (Ag/GC) that was transformed to AgNPs. In an acetate buffer solution, the cyclic voltametric analysis of AgNPs was examined. The experiment findings for GC and modified AgNPs were contrasted. The conductivity of AgNPs was investigated in an acetate buffer solution with a 0.15 M concentration. The generated AgNPs are uniform in size and stability. The produced AgNPs' electrochemical potential was shown.
