| DEVELOPMENT |
TAML activators have been developed around a different design concept compared to what nature uses in producing enzymes," "Nature designs around the big idea that any desired reaction can be sped up in the presence of myriad simultaneously occurring reactions. In contrast, we have followed the central design concept that reactions we do not want to occur in an oxidation process can be slowed down without suppressing the rate of the targeted reactions. After 20 years of catalyst design work, we are learning that this approach has considerable merit for solving problems in green oxidation chemistry." |
| ECOLOGY |
BLACK WATER The Tarawera River in New Zealand, flowing into the Pacific Ocean, is discolored by residual lignin discharged in treated wastewater from a paper mill. In a field trial, author et al are using a TAML activator to promote H2O2 to further degrade the lignin, resulting in a 50% reduction of color in the wastewater. |
| OBSERVATION'S | "TAML activators are water soluble, and different examples allow access to a broad pH range [1 to 13]," "The activators are relatively easy to synthesize, and they function well in nanomolar to low-micromolar concentrations." The activators can be readily modified to achieve a desired selectivity, he added, and for most applications minimal capital costs will be needed for their implementation. Initial lab tests indicate that the TAML activators have low toxicity, but complete toxicology studies to check environmental persistence and bioaccumulation are still needed. |
