Nano-photocatalysts' are particles of very small size that can degrade organic wastes and harmful microorganisms, when exposed to light. Titania is the most commonly used photocatalyst, but the limitation with existing titania is that it is mainly active in ultraviolet (UV) light. UV-light cannot be used for indoor applications because UV is mutagenic and causes cancer. This project will use an eco-friendly approach to develop novel titania nanoparticles, which will be active in visible light. Success will lead to new options in the management of our organic wastes and wastewaters (global problems), plant disease control, clean clinical surroundings, and add value to our day-to-day products like self-cleaning windows, and textiles.

纳米光催化剂是非常小的颗粒，当暴露在光下时，可以降解有机废物和有害微生物。二氧化钛是最常用的光催化剂，但现有的二氧化钛的局限性是它主要在紫外线（UV）光中具有活性。紫外线不能用于室内应用，因为紫外线是诱变性的，会导致癌症。该项目将使用一种生态友好的方法来开发新型的二氧化钛纳米颗粒，这种纳米颗粒在可见光下具有活性。成功将为我们的有机废物和废水（全球性问题）管理、植物病害控制、清洁的临床环境带来新的选择，并为我们的日常产品（如自清洁窗户和纺织品）增加价值。
