Photocatalysis large scale

Large-scale installations of air purification by Ti02 photocatalysis have been built and operated in North America by Trojan Technologies, Inc. (143) and United Technologies of Connecticut (144) (Fig. 6). The objective was to avoid polluting groundwater by chlorinated aliphatic... 

Abstract The use of semiconductor photocatalysis for treatment of water and air has been a topic of intense research activity over the past 20 years. This chapter provides a review of this highly effective technology. The fundamental processes involved in the technique are initially detailed with a discussion of some recent novel concepts in photocatalysis. A range of applications of water and air treatment are subsequently described with examples of mechanistic description of the major breakdown pathways of some key compounds. Examples of large-scale water treatment applications are also discussed. 

In particular, nonconcentrating CPC reactors are currently regarded as one of the best options for large-scale applications of solar photocatalysis, because they combine some advantages of both PTC and nonconcentrating reactors (Malato Rodriguez et al., 2004) as follows ...
