2 results about "Oxidation-Reduction Activity" patented technology

The application discloses a high-entropy oxide catalyst and a preparation method and application thereof. The high-entropy oxide containing Ni, Co and Mn is prepared by an oxalic acid coprecipitation method, oxalate and various transition metal ions are efficiently coordinated and precipitated, atomic-level uniform dispersion of metal elements is realized, a stable single-phase spinel structure is formed, and the oxidation-reduction activity, the lattice oxygen migration rate and the surface oxygen vacancy density of the material are greatly improved, and the deep degradation capacity of chlorobenzene is significantly enhanced.
