Abstract: Titanate nanotubes (TNT) were firstly prepared with anatanse particles (TO) as a
precursor by a concentrated alkaline hydrothermal method, and then anatanse titania nanotubes
(WTNT) were synthesized with TNT as a raw material by a microwave hydrothermal method. The
adsorption and photocatalytic degradation performance of tetracycline hydrochloride (TC) were
evaluated under dark condition and visible light irradiation. The products were characterized with
X-ray diffraction, transmission electron microscope, and UV-visible diffuse reflectance
spectroscopy, respectively. The results show that the as-prepared WTNT samples synthesized
under 2.0 MPa is single-crystalline anatase. The WTNT samples treated after microwave
hydrothermal treatment appear a hollow tubular structure with the outer diameter of 10 nm and
the length of approximately 100-200 nm. The band gap of TNT and WTNT are greater than that of
TO precursor. The adsorption process of TC on three catalysts can be described by a
pseudo-second-order kinetics model. The WTNT exhibits a superior photocatalytic degradation
capability to TC under visible light irradiation.
