An innovative hydrometallurgical process for the production of silver nanoparticles from spent silver oxide button cells

In view of the worldwide concern over the environmental impact of improper disposal of spent batteries, the production of value-added products from these metal-containing wastes can provide motivation for their efficient collection and recycling. In this study, the production of silver nanoparticles (AgNPs) directly from spent silver oxide button cell batteries via a leaching-purification-reduction method was investigated for the first time....
