Kinetics and Mechanism of Decomposition of Hydrogen Peroxide Catalyzed by fat Co3+and [Co(NH3)4]3+ Adsorbed on Alumina

Abstract

The decomposition of H₂O₂ at 30° catalyzed by Co³⁺ ions, adsorbed on alumina, exhibits first order kinetics with respect to [H₂O₂]. As the amount of surface adsorbed ions increases, the value of first order rate constant initially increases linearly, reaches a maximum and decreases thereafter. It is found that pH greatly influences the decomposition of H₂O₂ consistent with the kinetic data.
