Abstract

Cube shaped mesoporous anatase TiO2 was synthesized by hydrothermal technique at 180 degrees C/24 h in the presence of glucose followed by calcination at 600 degrees C/2 h. The particles were characterized by XRD, DTA/TG, Raman spectroscopy, N-2 adsorption-desorption study, FESEM and TEM. The BET surface area, pore volume and pore diameter of the calcined product were found to be 67.3 m(2) g(-1), 0.24 cm(3) g(-1) and 9 nm, respectively. The FESEM images exhibited cube shaped particles of size 300-600 nm. TEM images revealed the aggregation of 10-20 nm size particles in the cubes. The photocatalytic degradation of methylene blue (MB) and 4-chlorophenol (4-CP), the environmental pollutants was studied with the synthesized calcined product. It showed 93.9% and 92.9% photodegradataion of MB and 4-CP, respectively after 2 h of irradiation. (C) 2016 Elsevier B.V. All rights reserved.
