General description

Silver nanoparticles (Ag-NPs) have unique physical and chemical properties such as high thermal and electrical conductivity, chemical stability, catalytic activity, surface-enhanced Raman scattering, and nonlinear optical behavior. Ag-NPs are widely used in the fields of electronics, catalysis, and medicine.

Application

Silver can be used as a catalyst for the direct electroreduction ofcarbon dioxide.
