- Abstract
- The sol-gel synthesis of water-based sols of
nanocrystalline TiO 2 in a large pH range (1.3-10.6) was
carried out by acid hydrolysis of titanium(IV) isopropoxide
with acetic acid or malonic acid acting also as complexing
agents. Subsequent peptization was achieved in acid
medium, in the case of acetic acid, and in basic medium
(through triethylamine), in the case of malonic acid. The
TiO 2 particles were characterized using X-ray diffraction,
Raman, high-resolution transmission electron microscopy
and dynamic light scattering-electrophoretic light scatter-
ing. Methyl orange (MeO) and methylene blue (MB) were
used as model contaminants to investigate the degradation
activity of the different sols under UV irradiation. MB
molecules adsorbed on the TiO 2 surface of the basic sol
were found as trimeric species. The basic TiO 2 sol was
effective for the degradation of both dyes, whereas the acid
sols gave satisfactory results only for MeO. (literal)
