Summary:

This book demonstrates outstanding improvement of photo-catalytic degradative efficiency by the coupling of microwave (MW) radiation with the titania-coated electrode-less discharge lamps (EDLs). Titania thin film is used as the photo-catalyst due to its superior characteristics. The EDL as a novel light source generates efficiently UV/Vis radiation when placed into a MW field. Thin nanoporous titania films are prepared by dip-coating of EDL via a sol-gel method using titanium isopropoxide, or titanium n-butoxide, acetylacetone, and a transition metal acetylacetonate.
