  • Patent number: 11471854
    Abstract: The process of reacting nanoscale ce-MoS2 nanosheets anchored on oxide support with lead in solution at room temperature whereby the reaction is rapid and spontaneous resulting in the formation of PbMoO4-xSx in the process of scavenging Pb2+ and Pb4+ present in the solution.
    Type: Grant
    Filed: December 5, 2018
    Date of Patent: October 18, 2022
    Assignee: Indian Institute of Technology Madras (IIT Madras)
    Inventors: Thalappil Pradeep, Biswajit Mondal, Ananthu Mahendranath, Anirban Som, Sandeep Bose, Tripti Ahuja, Avula Anil Kumar, Jyotirmoy Ghosh
  • Patent number: 11351508
    Abstract: The present invention relates to a new method for creating nanopores in single layer molybdenum disulfide (MoS2) nanosheets (NSs) by the electrospray deposition (ESD) of silver ions on a water suspension of the former. Electrospray deposited silver ions react with the MoS2 NSs at the liquid-air interface resulting in Ag2S nanoparticles (NPs) which goes into the solution leaving the NSs with holes of 3-5 nm diameter. Specific reaction with the S of MoS2 NSs leads to Mo-rich edges. Such Mo-rich defects are highly efficient for the generation of active oxygen species such as H2O2, under visible light, which causes efficient disinfection of water. The holey MoS2 NSs shows 105 times higher efficiency in disinfection compared to normal MoS2 NSs. Developed a conceptual prototype and tested with multiple bacterial strains and a viral strain, demonstrating the utility of the method for practical applications.

  • Publication number: 20210205791
    Abstract: The present invention relates to an ambient ion based method of making free-standing 2D metal sheets made of bare NPs, at the air-liquid interface. An electro-hydrodynamic flow field was generated by electrospray deposition on the liquid surface, which in turn assisted the assembly of the NPs. The NP-NSs were made under ambient conditions at room temperature from metal salt precursors. The sheets can be made of different elements such as Pd, Au, and Ag. Synthesized 2D NP-NSs were used as efficient and reusable heterogeneous catalysts for C—C bond formation reactions. These thin metal sheets may also be used as catalysts, sensors, gas adsorbing media, electrodes for electrochemical reactions, etc.
