Abstract

The present disclosure relates to a method of disinfecting a fluid comprising at least one live microbial organism. The method includes contacting the fluid comprising the at least one microbial organism with an effective amount of a photo-catalyst while exposing the fluid and the photo-catalyst to light from at least one light source with a wavelength of about 300-550 nm to reduce the number of the at least one live microbial organism to a predetermined level. The photo-catalyst comprises tungsten trioxide nanoparticles doped with palladium nanoparticles, and the palladium nanoparticles are present in an amount of about 0.1-5% of the total weight of the tungsten trioxide nanoparticles and the palladium nanoparticles.
