Active TiO2 under visible light, as a key material for photoremediation
TiO2 nanoparticles were obtained from a simple sol-gel method, which not involve the use of structure directing agents neither a high final calcination temperature. The solids were characterized by XRD, UV-Vis, N2 adsorption-desorption, and TEM. These materials were tested in photocatalytic...

Active TiO2 Visible light Photoremediation |
description |
TiO2 nanoparticles were obtained from a simple sol-gel method,
which not involve the use of structure directing agents neither a
high final calcination temperature. The solids were characterized
by XRD, UV-Vis, N2 adsorption-desorption, and TEM. These
materials were tested in photocatalytic degradation of two organic
substrates: acid orange acid 7 (AO7) and paracetamol (PCT).
LED lamps were used as sources of visible radiation. The
parameters evaluated were the final calcination temperature as a
post-synthesis treatment, and the presence of iron along carbon.
A complete degradation of the two tested pollutants was achieved,
using the catalysts modified with iron, carbon, and calcined only at
200 °C. In this way, it was possible to activate the synthetized
mesoporous material with visible light, to be applied in an
advanced oxidation process, as is heterogeneous photocatalysis. |
