Abstract

Photocatalytic synthesis of silver-oxide clathrate Ag₇ O ₈ N O₃ was investigated. The process is based on photocatalytic enhanced oxidation of Ag+ in a AgN O₃ aqueous solution using a titanate-based photocatalyst (SrTi O₃) single crystal. By doping the crystal with Nb or La, the photocatalytic production of Ag ₇ O₈ N O₃ is enhanced even for relatively low concentrations of AgN O₃ aqueous solutions and more with higher Nb doping. This photocatalytic reaction can be understood in terms of selectivity of the oxidation reaction, favoring generation of O₂ or Ag ₇ O₈ N O₃, with the Nb doping as well as the concentration of the AgN O₃ aqueous solution having strong impact on the reaction selectivity.
