AgNPs of varying morphologies such as spherical, triangular, cubic and rod-like nanoparticles are used due to the difference in surface area and active sites available which affect the catalytic and adsorption ability . Among these spherical AgNPs are used widely due to their uniform distribution and stability. These nanoparticles provide moderate reactivity and are effective in adsorption-based removal . Rod-shaped AgNPs have enhanced surface area as compared to spherical AgNPs, which enhances its interaction with organic pollutants like phenolic compounds. However, the efficiency of nanostructures depends on dispersion stability . Triangular and cubic AgNPs have high surface energy as they have more exposed facets, therefore they tend to exhibit better catalytic and adsorptive properties as compared to spherical silver nanoparticles . Optimization of both morphology and size of AgNPs is essential for high efficiency in phenolic removal.
