Hydrothermal Preparation and Characterization of Nanocrystalline TiO2 Powder and its Photocatalytic Degradation of Alizarin Salt Dye Under UV-Light

Abstract

Titanium dioxide (TiO2) can be used as a photocatalyst because of its semiconductor property. In this work, pure anatase-TiO2 nanoparticles were synthesized by hydrothermally process at 210 degrees C in 90 min. The structural and physico-chemical properties of anatase-nano-titanium dioxide were determined by powder XRD, FTIR, BET and SEM analyses. Titanium dioxide particles were coated to the stainless steel plates by dip coating technique. The photocatalytic performance of the mono layer coated plates were tested for degradation of alizarin salt dye in solution under UV-light.
