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

Ozone is seen an a safer and more environmentally friendly alternative to chlorine for water disinfection, but the efficient generation of ozone on-demand and at commercially relevant scales has been hindered by catalytic degradation problems. A team of researchers from Drexel University, University of Pittsburgh and Brookhaven National Laboratory has used quantum chemistry modeling to elucidate the atomic-scale features of electrodes used in the generation of ozone from water electrolysis.
