Atmospheric Corrosion of Silver and Silver Nanoparticles

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 (OCS) to form the (Ag2S) acanthite. Other aspects of environment, relative humidity presence oxidizing species, also play critical role. With emergence nanoparticles for range technological medical applications, there has been revival interest corrosion behavior this important metal. This article reviews current understanding atmospheric both bulk nanoparticle forms. Gaps our areas future investigation are identified.
