While ozone itself is a strong oxidant, the efficiency of ozone-based reactions can be enhanced by using catalysts. Common catalysts include: 1. Transition Metals: Metals like iron (Fe), cobalt (Co), and manganese (Mn) can enhance the decomposition of ozone, increasing its reactivity. 2. Metal Oxides: Oxides like titanium dioxide (TiO2) and cerium oxide (CeO2) are used to support ozone-based oxidation reactions. 3. Activated Carbon: This material can adsorb ozone and organic pollutants, facilitating their reaction.
