Advanced Oxidation Processes (AOPs)
AOP technologies produce strong oxidants including hydroxyl radicals, sulfate radicals and high valent metal species to either realize complete mineralisation of organic pollutants (to carbon dioxide) or render them more biodegradable. The generation of active oxidants depends on external energy input or catalyst addition. CTET is engaged in the development and optimisation of a suite of Advanced Oxidation Processes that can transform non-biodegradable and toxic organics to less harmful products including catalytic ozonation, Fe-based and “green” Fenton and anodic oxidation processes.
Silver/silver halide based photocatalysts generate reactive oxidants such as chlorine and/or carbonate radical with these species capable of inducing oxidation of organic contaminants on irradiation by visible light.
Biomimetic ligands for oxidative degradation take inspiration from natural biological enzyme motifs to generate ligands that are both oxidatively robust and capable of stabilizing highly oxidizing high-valent metal species. The oxidizing form can be catalytically generated from the resting state in many ways and employed to degrade a broad variety of contaminants.
