英文摘要: This paper reports the results of a field test study concerning the use of photocatalytic paving elements in Denmark to mitigate nitrogen oxides pollution. Prior to the installation, the photocatalytic concrete elements were tested in the lab, where conversions of NO reached values as high as 78% with low amount of NO2 formed. Once installed, nitrogen oxides concentration, temperature and relative humidity were monitored every minute for more than a year. The results of the field tests showed that under ideal weather and irradiation conditions, i.e. summer months, the monthly average NO concentration (based on day and night values) in proximity of the photocatalytic area was around 22% lower than the reference area. The close correlation between performance data and solar UV irradiance revealed that at such a latitude (55.68° N) adequate NO (hence NOx) conversions (monthly average) are achieved for total UV irradiance exceeding 600kJm-2day-1. Within this period, data relative to the solar noon showed instantaneous NO abatement in some cases higher than 45%, corresponding to a total NOx abatement higher than 30%. © 2015 .
