  • Patent number: 10661265
    Abstract: Semiconductor-Oxides Nanotubes-Based Composite Particles Useful for Dye-Removal and Process Thereof, has been described in this invention, which relates to an innovative method, involving an ion-exchange mechanism operating under the dark-condition in an aqueous solution, for the processing of innovative products consisting of the nanotubes of semiconductor-oxides deposited on (or anchored to or attached to) the surface of flyash particles and metal-oxide (magnetic and non-magnetic) nanoparticles. The resulting micro-nano and nano-nano integrated composite particles find potential application in the removal of an organic synthetic-dye from an aqueous solution and industry effluent via the surface-adsorption process, involving the ion-exchange and electrostatic-attraction mechanisms, operating in the dark-condition.
    Type: Grant
    Filed: March 16, 2018
    Date of Patent: May 26, 2020
    Assignee: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCH
    Inventors: Satyajit Vishnu Shukla, Hareesh Padinhattayil, Harsha Narayani, Manu Jose, Remya Karunakaran

  • Patent number: 9993814
    Abstract: Semiconductor-oxide nanotubes-based composite particles are useful for dye-removal. A method involves an ion-exchange mechanism operating under a dark-condition in an aqueous solution, for the processing of products consisting of the nanotubes of semiconductor-oxides deposited on, anchored to or attached to the surface of fly ash particles and metal-oxide (magnetic and non-magnetic) nanoparticles. The resulting micro-nano and nano-nano integrated composite particles can be used in the removal of an organic synthetic-dye from an aqueous solution and industry effluent via a surface-adsorption process, involving ion-exchange and electrostatic-attraction mechanisms. The composite particles can be recycled for the next cycle of dye-adsorption by decomposing the previously adsorbed dye on their surfaces via the use of either noble-metal-deposited or magnetically separable magnetic photocatalysts and exposure to ultraviolet (UV) or solar-radiation.
