Catalytic Decomposition Kinetics and Mechanism of Hydrogen Peroxide by Modified Activated Carbon
Modified activated carbon composites were prepared and their catalytic properties were evaluated in the H2O2 decomposition. Activated carbon alone showed very low activities compared to iron and manganese oxides / activated carbon composites, suggesting that the presence of Fe and Mn in the oxide plays an important role for the activation of H2O2. The presence of Mn in the composite structure produced a remarkable increase in the reactivity. The obtained results showed that the peroxide decomposition catalyzed by GACFM met pseudo-first-order kinetic and the maximum OH· production was on GACF1M3.The decomposition mechanism of H2O2 was analyzed in detail.
