A residue-free approach to water disinfection using catalytic in situ generation of reactive oxygen species
Despite its biocidal properties, the use of hydrogen peroxide is still limited in the context of water disinfection. Here an approach is disclosed based on the generation of H2O2 in situ by means of an AuPd catalyst, which can compete with chlorination methods by generating a highly reactive radical flux.
