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 16):
A process for a preparation of the nanocomposite particle of  claim 15 , comprising:\n (a) dispersing 0.5-10 g\u00b7l \u22121  of metal-oxide nanoparticles in water having a neutral solution-pH (of about 6.5-7.5) under continuous stirring for 5-30 min at temperature in a range of 20-30\u00b0 C.; (b) adding 0.5-10 g\u00b7l \u22121  of hydrothermally processed nanotubes of semiconductor-oxides in the suspension obtained in said (a) under continuous stirring for 5-30 min at temperature in a range of 20-30\u00b0 C., followed by sonicating the suspension for 5-30 min, subsequently stirring the suspension continuously for 1-10 h in a dark-condition to obtain the semiconductor-oxide nanotubes-metal oxide nanocomposite particles; (c) separating the semiconductor-oxide nanotubes-metal oxide nanocomposite particles using a centrifuge operated at 2000-4000 rpm or an external magnetic field, followed by washing the nanocomposite particles using water for 30 min-2 h till a pH of filtrate remains unchanged or neutral, followed by separation and drying the nanocomposite particles in an oven at 70-90\u00b0 C. for 10-15 h.
