Differing from their bulk metal counterpart silver nanoparticles show unique properties such as strong surface plasmon resonance (SPR), which arises from the collective oscillation of conduction electrons in response to incident light. This property enhances the ability of AgNPs to interact with organic molecules facilitating photolytic and adsorption-based removal of phenolic compounds . SPR also contributes to improve electron transfer, which is essential for oxidative degradation mechanisms.
