The present invention relates to a new method for creating nanopores in single layer molybdenum disulfide (MoS.sub.2) nanosheets (NSs) by the electrospray deposition (ESD) of silver ions on a water suspension of the former. Electrospray deposited silver ions react with the MoS.sub.2 NSs at the liquid-air interface resulting in Ag.sub.2S nanoparticles (NPs) which goes into the solution leaving the NSs with holes of 3-5 nm diameter. Specific reaction with the S of MoS.sub.2 NSs leads to Mo-rich edges. Such Mo-rich defects are highly efficient for the generation of active oxygen species such as H.sub.2O.sub.2, under visible light, which causes efficient disinfection of water. The holey MoS.sub.2 NSs shows 10.sup.5 times higher efficiency in disinfection compared to normal MoS.sub.2 NSs. Developed a conceptual prototype and tested with multiple bacterial strains and a viral strain, demonstrating the utility of the method for practical applications.
