Abstract

Abstract: A particular bird's nest-like pseudo-boehmite (PB) composed of cohesive nanostrips was prepared by a novel and facile approach based on the reaction of Al–Ga–In–Sn alloy and water, together with ammonium carbonate. The PB possesses a large specific surface area (465.2 m 2 g −1 ), pore volume (1.0 cm 3 g −1 ), and pore diameter (8.7 nm). Subsequently, it was utilized as a precursor to form the TiO2 / γ -Al2 O3 nanocomposite for tetracycline hydrochloride removal. The removal efficiency can reach above 90% at TiO2 :PB = 1:1.5 under the Sunlight irradiation simulated by a LED lamp. Our results indicate that the nest-like PB is a promising carrier precursor for efficient nanocomposite catalysts.
