Rational design of a bismuth oxyiodide (Bi/BiO1-I) catalyst for synergistic photothermal and photocatalytic inactivation of pathogenic bacteria in water

In this study, bismuth oxyiodide with coexistence of plasmonic Bi and oxygen vacancy (Bi/BiO1-xI) was successfully prepared and used towards photothermal and photocatalytic disinfection of pathogenic bacteria containing water. Plasmonic Bi and oxygen vacancies in Bi/BiO1-xI induced a surface plasmon effect under the irradiation of simulated solar light from 500-900 nm and promoted the generation of hot electrons and reactive species (1O2, h+ and...
