A strategy for modulating the catalytic active center of AP thermal decomposition and its application: La-doped MgCo₂O₄

Abstract

La diffuses into the main lattice of MgCo 2 O 4 (La x -MgCo 2 O 4 ), exposing more Co 3+ active centers: (1) La 3+ , O 2 − , high Co 3+ concentration, high conductivity promote AP decomposition. (2) The highly active La x -MgCo 2 O 4 becomes potential catalyst for CSPs.
