Abstract
A synthetic catalyst providing superoxide dismutase activity consists essentially of monodispersed nanoparticles of cerium oxide having a crystal lattice containing cerium in mixed valence states of Ceand Cewherein the Cevalence state predominates and containing an enhanced Ce/Ceratio and an effective number of oxygen vacancies in the crystal lattice so as to increase catalytic efficiency. A method of making the synthetic catalyst includes dissolving hydrous Ce(NO)in water so as to form a solution, stirring the solution, adding hydrogen peroxide, heating and stopping when the solution develops a light yellow color.
