Photocatalyst efficiencies in concrete technology: The effect of photocatalyst placement

(چکیده مقاله) :
Abstract :

The application of photocatalysts in concrete technology is by now a well-established concept. However, despite
the great opportunities for air quality improvements to be derived from the considerable concrete surfaces
exposed to the atmosphere, particularly in cities where air quality is greatly affected by vehicle exhaust and
industrial emissions, photocatalytic concretes are still not in mainstream application. With current levels of NOx
pollution considerably exceeding EU legislative guidelines in urban centres throughout the industrialised world,
it is important to consider what the issues are. The likely barriers to more widespread implementation are likely
to include cost effectiveness, which needs to be related to photocatalyst impact, but the challenges in measuring
impact on air quality directly are complex. This paper seeks to place photocatalytic efficiencies into context,
comparing performances of the conventional photocatalyst dispersion in surface mortar coatings with that of
photocatalysts supported on surface exposed aggregates. The nature and impact of catalyst binding to the aggregate is also discussed.
