Investigating the mechanism of catalytic reduction of silver nitrate on the surface of barium titanate at room temperature: oxygen vacancies play a key role†
Abstract
In this study, the formation mechanism of Ag nanoparticles deposited on Barium Titanate (BT) surface was investigated. The surface oxygen vacancies of BT linked with the hydroxyl oxygen of ethylene glycol and catalyzed the reduction of silver nitrate, leading to promoted deposition of Ag nano particles on the BT surface.
