✦ Synopsis

for acetaldehyde which is 2-3 times greater than that achieved by conventional catalysts. Japan Chemical Week, 15 Sep 2005, 46 (2334), 2 Visible light photocatalytic titania developed Sekisui Jushi (Japan) has developed a type of titania photocatalyst which responds to visible light. It incorporates iron and sulfur. It is very effective for decomposing formaldehyde. Japan Chemical Week, 6 Oct 2005, 46 (2337), 2

As clean as concrete

Chemical reactions involving photocatalysts now make various selfcleaning surfaces possible. The construction and prefabricated building industries are particularly confident that this technology will open up new market opportunities. Cement surfaces that have been treated with a photocatalytic material are self-cleaning in that materials cannot adhere to them. Kemira's titanium dioxide research has increasingly shifted towards developing applications. It is believed that the capacity for self-cleaning will have a profound impact on the construction industry in terms of its aesthetic image.
