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