Abstract: A method for manufacturing silver-modified cerium oxide nanoparticles (AgCNP2). The method includes ageing un-aged cerium oxide nanoparticles in a solution with silver nitrate and uses an accelerant. The accelerant speeds up peroxy ligand conversion of cerium oxide nanoparticles having a predominant 3+ cerium charge and accelerates evolution of all, to 1ppm or less of the limit of detection, ionized Ag to crystallize onto cerium oxide nanoparticles as a non-ionized stable metallic silver phase to form the AgCNP2. The accelerant can be low heat of 90°-115°F applied to the solution only after crash-out of the solution that is without an ingredient that incudes wholly un-stabilized hydrogen peroxide; wholly un-stabilized hydrogen peroxide mixed in the solution prior to aging; low heat of 90°-115°F applied to heat the solution that incudes wholly un-stabilized hydrogen peroxide; and a form factor (FF) ratio of a vessel of the closed system where the ageing takes place.
