Chapter 9: How Far Are We From Large-Scale PMR Applications?

Forty five years after successfully using titanium dioxide (TiO2) for the photoelectrochemical splitting of water (Fujishima and Honda, 1972), heterogeneous photocatalysis has received great attention by the scientific community as a promising green technology for environmental and energy applications. Numerous investigations have been carried out focusing on the removal of harmful water pollutants – organic (Kanakaraju et al., 2014; Ribeiro et al., 2015; Kaur et al., 2016) and inorganic (Cappelletti et al., 2008; Litter, 2017) – and on water disinfection (Kikuchi et al., 1997; Rincon and Pulgarin, 2004; McCullagh et al., 2007), as well as on the synthesis of industrially significant chemicals (Lu and Yao, 2014; Friedmann et al., 2016) and on hydrogen generation (Ahmad et al., 2015).
