ChemInform Abstract: Catalytic Activity of Pure Copper Oxide and Samples Containing Different Concentrations of Aluminum Oxide in Heterogeneous Decomposition of Hydrogen Peroxide

ChemInform Abstract

is determined and correlated with the non-stoichiometry of the different samples and electrical conductivity measurements. The structural properties of the catalysts are investigated employing DTA and IR techniques. The result shows that Al³⁺ is responsible for lowering the change carrier concentration (positive holes) which affects the capability of the catalyst's surface to adsorb oxygen. The surface adsorbed oxygen (as O2^- or O^2-) plays a decisive role in the H₂O₂ decomposition reaction (proposition of a three-step mechanism).
