Ph otocatalytic degrad ation of co ngored under UV and Visible light using Mo and S codoped TiO۲ nanoparticles

Dyes are one of main sourc es of water pollutants existing in our enviro nment.For water purifi cation treat ment variou s technologies are in use[۳]. Titanium dioxide is a veryactive photo catalyst,phy sical and chemical stability, inexpe nsive and of low biological toxicity[۱,۲]. The different morphologies of TiO۲ nan oparticles is used as photocatalyst. Heterogeneous photo catalysis by TiO۲ semiconductors is pro mising for elimination of hazardous environmental pollutants in air and wa ter [۳,۴]. In recent years,many experimental and research studied have been conducted to improve the photocatalytic activity of TiO۲,this paper follow s this purpose.
