“…This approach has economic and sustainability advantages in comparison with processes involving ozone generation, lamps or electrodes, which require high energy costs (Marin et al, 2011). Another advantage is the possible disinfection of water contaminated with pathogenic microorganisms (McCullagh et al, 2007;Rincón and Pulgarin, 2004). Therefore, suppressing the recombination of photo-generated charge carriers, as well as the efficient utilization of visible light, are some of the main challenges to develop economically feasible photocatalytic processes.…”

Environmental pollution is a recognized issue of major concern since a wide range of contaminants has been found in aquatic environment at ng L −1 to μg L −1 levels.In the year 2000, a strategy was defined to identify the priority substances concerning aquatic ecosystems, followed by the definition of environmental quality standards (EQS) in 2008. Recently it was launched the Directive 2013/39/EU that updates the water framework policy highlighting the need to develop new water treatment technologies to deal with such problem. This review summarizes the data published in the last decade regarding the application of advanced oxidation processes (AOPs) to treat priority compounds and certain other pollutants defined in this Directive, excluding the inorganic species (cadmium, lead, mercury, nickel and their derivatives).The Directive 2013/39/EU includes several pesticides

“…Since then, there have been a large number of research studies reporting the use of photocatalysis to inactivate microorganisms including bacteria (cells (8,9), spores and biofilms (10), viruses (11), protozoa (12), fungi (13) and algae) (14). Photocatalytic disinfection has been reviewed by several researchers including Byrne et al (15), McCullagh et al (16), Malato et al (17) and Robertson et al (18). The majority of published research papers have focused on the assessment of novel materials, new reactor systems or the effect of experimental parameters on the rate of inactivation.…”

The lack of clean and safe drinking water is responsible for more deaths than war, terrorism and weapons of mass destruction combined. This suggests contaminated water poses a significant threat to human health and welfare. In addition, standard water disinfection approaches such as sedimentation, filtration, and chemical or biological degradation are not fully capable of destroying emerging contaminants (e.g. pesticides, pharmaceutical waste products) or certain types of bacteria (e.g. Cryptosporidium parvum). Nanomaterials and nanotechnology based devices can potentially be employed to solve the challenges posed by various contaminants and

“…TiO 2 photoactivity reaction assists the intrusion of the copper ions into the cell, which is probably the cause of the destruction of the E. Coli colonies even under very weak UV light. Actually several nanostructured TiO 2 derivatives are studied and applied as germicidal species, especially on the treatment of water contaminated with pathogenic microorganisms presenting a potential hazard to animals and human beings (Mccullagh et al, 2007;Skorb et al, 2008).…”
