Resumo

CHANG, Wei; ZHANG, Maojin; REN, Xiaosai  e  MILLER, Andrew. Synthesis and photocatalytic activity of monolithic Fe2O3/TiO2. S.Afr.j.chem. (Online) [online]. 2017, vol.70, pp.127-131. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2017/v70a18.

The monolithic Fe2O3/TiO2 composites were synthesized via a one-pot sol-gel process with titanium tetrachloride as a Ti source and ferric chloride as a Fe source. The monolithic Fe2O3/TiO2 composites were characterized by scanning electron microscopy, powder XRD, N2/adsorption-desorption, fluorescence and UV-vis diffuse reflectance spectroscopy. The photocatalytic activity of the Fe2O3/TiO2 composites were evaluated by degradation of bisphenol A. The results indicated that, with the doping of Fe, the surface area of the monolithic Fe2O/TiO2 increased, the forbidden band width decreased and the electron-hole recombination rate decreased. The monolithic Fe2O3/TiO2 composite with Fe/Ti molar ratio of 0.03 had the best photocatalytic activity for degradation of bisphenol A.

Palavras-chave : Sol-gel process; Fe2O3/TiO2; photocatalysis.
