Catalytic sterilization and disinfection

A series of Ag-loaded catalysts with different crystal phases and shapes were prepared, and their bactericidal activities were investigated at room temperature. The bactericidal effect should be considered as a synergic action of reactive oxygen species (ROS) produced through activating O2 by catalysts and the toxicity of Ag+ eluted from the catalysts, which could induce the production of intracellular ROS, disruption of cell walls and cell membranes, and cell death. FT-IR results also indicated the production of CO2, which proved that catalytic oxidation is the essential mechanism in the bactericidal process.  (Catal. Commun., 2004, 5(3), 170; Environ. Sci. Technol., 2008, 42, 1699; J. Inorg. Biochem., 2014, 135, 45)
