ABSTRACT
Heterogeneous catalysis involving semiconductors has been developed in the last 10-15 years due to its potential applications to environmental problems (Oancea and Oncescu, 2008). In recent years, advanced oxidation processes (AOPs) have been proposed as attractive alternatives for the treatment of contaminated ground-, surface-, and wastewater containing pesticides or non-biodegradable organic pollutants (Phanikrishna Sharma et al., 2008a). Among the most used processes are heterogeneous photocatalysis.
