Abstract
Our world extremely suffers from pollution due to urgent need to industry and discharge of factories waste, so most of scientific researches are concerned in solving this crisis. In the last decades, semiconductor-assisted photocatalysis was intensively studied as a ‘green’ method for wastewater treatment.
Titanium dioxide (TiO2) is one of the most important photocatalysts due to its non-toxicity, availability, stability and excellent photocatalytic performance. Unfortunately, it has two major disadvantages: its rapid electron-hole recombination rate causing decreasing of its photocatalytic efficiency and its large band gap energy (3.2 eV for pure anatase) causing excluding its activity only under UV irradiation which represents only 2–3% of whole solar-light spectrum.
Several techniques are used to overcome these disadvantages
