摘要

•Silver diammine complexes adsorbed electrostatically onto oxides yield the smallest particles.•Deposition of Ag(H2O)2+/Ag(NH3)2+ species over carbon at any pH is reactive and results in large particles.•Silver aquo complexes adsorb via ion exchange near the PZC of alumina, zirconia, and niobia.•Ag2O can be thermally spread over alumina and niobia via calcination.
