Abstract
The worldwide high demand for drinking water has led to the development of numerous
advanced wastewater treatment processes. Photocatalysis has recently become an alternative
and attractive technique for green energy production and environmental remediation. It is also
a wastewater treatment technique which is considered reliable and is expected to provide a
sustainable solution to the scarcity of clean water. In particular, heterogeneous photocatalysts
based on TiO2 nanoparticles and sunlight have been proposed as a powerful technique for
degradation and mineralisation of persistent organic pollutants (POP`s). Although this method
seems promising, some critical challenges are still to be addressed: namely, low photoefficiencies,
faster electron and hole (๐‘’โˆ’โ„โ„Ž+) pair recombination, utilisation of UV light and
catalyst removal after treatment of pollutants.
