Rational design of a bismuth oxyiodide(Bi/BiO1-xI)catalyst for synergistic photothermal and photocatalytic inactivation of pathogenic bacteria in water
文献摘要：
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 bac-teria 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 elec-trons and reactive species(1O2,h+and·O2-).The catalyst showed promising performance for inactiva-tion of E.coli K-12,with a 7.2 log inactivated achieved under the optimum conditions.A synergy between photothermal and photocatalytic inactivation was identified and discussed.The mechanisms of E.coli K-12 destruction were investigated.The destruction of extracellular antioxidant enzymes of E.coli K-12 was identified after inactivation.Moreover,the E.coli's membrane and its intracellular contents were attacked by the reactive species(1O2,h+and·O2-)and the thermal effects.This work provides useful insights into the rational design of semimetal bismuth-mediated photocatalysts towards effective and sustainable water disinfection.
