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. 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.

Claim (Index 18):
A process for a surface-cleaning and a recycling of the nanocomposite particle of  claim 17  after an adsorption of an organic synthetic-dye from an aqueous solution via a surface-adsorption mechanism operating in a dark-condition, comprising:\n (a) suspending 1-30 g\u00b7l \u22121  of nanocomposite particles having a surface-adsorbed organic synthetic-dye (0.1-3 mg\u00b7g \u22121 ) in water under continuous stirring for a period ranging between 5-30 min at temperature ranging between 20-30\u00b0 C.; \n (b) suspending a photocatalyst (10-60 wt. % of total weight of suspended solid particles) selected from the group of a nanocrystalline anatase-TiO 2 -coated SiO 2 /\u03b3-Fe 2 O 3  magnetic photocatalyst or a noble-metal-deposited nanocrystalline anatase-TiO 2  in the suspension obtained in said (a) under continuous stirring, followed by sonicating the suspension for 5-30 min, subsequently stirring the suspension continuously under UV or solar-radiation exposure for 1-10 h; \n (c) centrifuging the solution at 2000-4000 rpm to separate the nanocomposite particles and photocatalyst together, followed by washing using water for 30 min-2 h multiple-times until the pH of filtrate remains unchanged or neutral; \n (d) separating photocatalyst particles from the surface-cleaned nanocomposite particles using an external magnetic field; and \n (e) drying both the photocatalyst particles and nanocomposite particles in an oven at 70-90\u00b0 C. for 10-15 h for reuse.
