Recent years, steadily growing energy crisis has directed a global trend toward sustainable
development. With the ability of semiconductor particles and recently with perovskites to
create electron hole pairs upon irradiation with artificial light, the sun, gives solutions for
clean drinking water and improved air quality.
Solution based synthesis by ethylene – glycol route at room temperature of a series of
samples (such as titanates ATiO
3
and vanadates AVO3) with different ration transition metals
(such as Mn, Ce, etc) followed by calcination at 600
o
C in air, obtaining different
morphologies.
The perovskite oxides were characterized with X-Ray powder diffraction (XRD), Scanning
Electron Microscopy (SEM), UV-VIS Spectroscopy. Experiments showed that the
perovskites presented a stronger photocatlytic ability for the degradation of organic
molecules, including 4-nitrophenol, Phenol and Methylene Blue under Visible and UV
irradiation.
