Title: Catalytic inactivation of SARS coronavirus, Escherichia coli and yeast on solid surface Cord-id: qa4rq9uu Document date: 2004_2_3
ID: qa4rq9uu
Snippet: Catalytic oxidation is a potential way to disinfect air through a air-condition system. We find that the SARS coronavirus, bacteria and yeast are completely inactivated in 5 min on Ag catalyst surface and in 20 min on Cu catalyst surface at room temperature in air. Scanning electron microscopy (SEM) images show that the yeast cells are dramatically destructed on the Ag/Al(2)O(3) and Cu/Al(2)O(3) surfaces, which indicates that the inactivation is caused by catalytic oxidation rather than by toxic
