Summary, etc. <p>Mesoporous titania (TiO<sub>2</sub>) hollow microspheres have been prepared by<em> </em>sol-gel method and characterized by XRD, Raman, FTIR, N<sub>2</sub> adsorption-desorption study, FESEM, TEM and UV-DRS. The FESEM images reveal hollow spherical shaped particles of size 2–4 µm. The BET surface area, total pore volume and average pore diameter of 400 °C-treated sample are found to be 74.52 m<sup>2</sup> g<sup>-1</sup>, 0.23 cm<sup>3</sup> g<sup>-1</sup> and 12.37 nm, respectively. The band gap energy of the product is calculated as 3.06 eV. The prepared TiO<sub>2</sub> hollow spheres show ~90% photodegradation of the water pollutant, 4-chlorophenol, within 1 h. The photocatalytic reaction shows pseudo-first order reaction with a rate constant of 0.027 min<sup>-1</sup>. The photocatalytic experiments repeated for another three cycles showed no significant changes in the <em>k</em> (min<sup>-1</sup>) values, indicating the potential reusability of the material.</p>
