- Additional information
- The output arises from an EPSRC cooperative project with the Department of Chemistry, Aberdeen University. The output describes the fundamental catalysis science of using a TiO2 nano-photocatalyst in a novel exposure by mounting on exposed aggregates. This methodology gave significantly higher efficiency compared to paste inclusion and hence overcomes the problem of UV occlusion of the bulk of the catalyst inside the concrete cover. Mounting the photcatalyst on an exposed aggregate resulted in 9 times higher degradation of NOx (De-NOx), equivalent to around 150 times greater utilisation efficiency, than that of TiO2 in traditional photocatalytic mortar (with a 5% loading).
