The lecture will focus on environmental applications of TAML oxidant activators. TAML activators catalyze oxidation reactions in water of a wide range of industrially significant oxidants; oxygen, peroxides, ozone, and others. TAML activators are nontoxic transition metal catalysts with comparative peroxidase-like and catalase-like behavior that translates into unprecedented technical performance in large-scale oxidation applications. TAML activators have molecular weights of ca. 500 u, are capable of thousands of turnovers per minute with H2O2, and exhibit a new chemistry of iron with oxygen. I will briefly sketch our understanding of TAML catalysis and research aspects of their reduction to practice for selected uses. These will include applications in the pulp and paper and textile industries, disinfection and homeland defense (spore killing and chemical warfare agent inactivation), the destruction of priority organochlorine pollutants and thiophosphate pesticides, and the desulfurization of gasoline and diesel fuels.
