This sustainable, supercharged catalyst cleans up mold

By Mary Page Bailey |

A family of oxidation catalysts known as TAML has been revamped to increase activity by several orders of magnitude, even at very dilute catalyst concentrations. Developed by Sudoc (Cambridge, Mass.; www.sudoc.com), these peroxidase-mimicking catalysts present a more environmentally sustainable option in challenging cleaning and treatment applications, such as mold treatment, where toxic chemicals are typically required, says Roger Berry, CEO of Sudoc. “Because of its oxidative characteristics, the catalyst acts as a ‘super-cleaner.’ Our team has formulated a very powerful mold cleaner that uses significantly less hypochlorite than other products on the market,” adds Berry. The key to TAML catalysts’ performance alongside oxidants is an iron atom surrounded by a macrocyclic amide-containing ligand, which makes the catalyst extremely active in oxidation reactions, but also very resilient, especially compared to other transition-metal oxidation catalysts, explains Matt Mills, Sudoc’s director of research and development. The combination of activity and resilience comes after decades of iterations to pinpoint the weak points in the macrocycle and formulate a structure optimized to survive in conditions where other catalysts…
