摘要： 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. The novel composite particles can be recycled for the next-cycle of dye-adsorption by decomposing the previously adsorbed-dye on their surfaces via an innovative approach involving the use of either noble-metal-deposited photocatalyst or a magnetically separable magnetic photocatalyst and an exposure to the ultraviolet (UV) or solar-radiation.
