Nanoparticles in heterogeneous photocatalytic treatment

Ensuring reliable access to affordable and safe sources of water is critical to both global health and economic development. Chemicals of emerging concern (CECs) have come in the agenda as an emerging issue [1] to evaluate performance of water treatment processes that urge the use of advanced technologies using new materials such as nanoparticles [2]. “Nano” particles have particular aspects that are favored as high surface areas, hyper-catalytic functions, tunable physical properties and faster kinetics [3]. Photocatalyst materials have been adapted for visible light activated disinfection by dye sensitized, plasmon sensitized and semiconductor sensitized routes. The mechanism of reactive oxygen specie (ROS) generation in these materials is generally driven through oxygen reduction reactions by electron injected into the conduction band of the host semiconductor. Semiconductors are stable under illumination, typically metal oxides, usually consist of the top of the valence band located at +3 eV or lower and most widely used as photocatalysts which can drive redox reactions under visible light (>400 nm) [4]...
