An alternative material to increase the photocatalytic performance of TiO2
![1 Occurrence of semi-conductive photocatalytic reactions [3]](https://www.zkg.de/imgs/101549598_ef25d25582.jpg)
The Adana Cement R&D group is working on a material that is able to boost photocatalytic performance of cement, yet costs less than TiO2. This material was named the “TiPlus”. Use of TiPlus not only increases performance, but also replaces TiO2 to a large extent and is able to reduce production cost by 21-37 % depending on the preferred level of performance. It is thought that photocatalytic cement will be used more widely in the industry thanks to this reduction in its production cost.
1 Introduction
It is nowadays possible to maintain concrete surfaces clean and spotless for years. Concrete structures with such clean surfaces can be obtained by using properties of self-cleaning cement, which is able to break down organic dirt that piles up on concrete surfaces and keep the surface clean by displaying photocatalytic features under sunlight. In the meantime, it is able to photocatalytically convert NOx compounds into harmless compounds, drive them away and reduce NOx concentrations present in the air, thanks to the nano-sized TiO2 particles in its content. Self-cleaning cement...
