Quantum chemistry helps uncover path to safer ozone-based water disinfection

Researchers from Drexel University, the University of Pittsburgh, and Brookhaven National Laboratory used quantum-chemistry modeling to reveal atomic-scale features of electrodes for generating ozone via water electrolysis, addressing catalytic degradation that has hampered efficient, on-demand, commercially scalable ozone production. The insights point to a path for safer, more environmentally friendly ozone-based water disinfection as an alternative to chlorine.

What changes—technical or regulatory—would most accelerate utilities’ adoption of ozone disinfection if more durable, efficient electrodes became available?
