Atmospheric Corrosion of Silver and Silver Nanoparticles

Corrosion and Materials Degradation, 2022
Even though it is a noble metal, silver will corrode in ambient atmospheres, predominantly by reacting with sulfur-containing gases such as hydrogen sulfide (H2S) and carbonyl sulfide (OCS) to form the silver sulfide (Ag2S) acanthite. Other aspects of the environment, such as relative humidity and the presence of oxidizing species, also play a critical
