DESCRIPTION OF THE PROJECT

Background:

Air pollution causes harm to both health and

environment. A significant proportion of Europe’s

population live in areas such as cities where

exceedances of air quality standards occur. This puts

those populations at health risk, particularly from

ozone, nitrogen dioxide and particulate matter

pollution. The need to reduce air pollution remains an

important issue. The effects caused by air pollution

depend mainly on the concentration of pollutants,

chemical nature, exposure time and temporal

fluctuations on their concentration, and also on the

receptor sensitivity and synergisms between

pollutants. The primary pollutants are oxides of

nitrogen (NOx) mainly nitrogen monoxide (NO), and

volatile organic compounds (VOC).

Objectives: To demonstrate, at a pilot scale, the environmental possibilities of a new

range of porcelain ceramic in reducing nitrogen oxides present in the

atmosphere.

To conduct studies about the efficiency of BIONICTILE-OFFNOx porcelain

ceramic in reducing nitrogen oxides present in the atmosphere under

representative conditions of an urban environment in terms of daily NOx

pattern concentration, humidity and radiation (city of Valencia), using the

Atmospheric Simulation chamber EUPHORE (European PHOto-REactor)

Results

• A decrease in the levels of nitric acid (HNO3)

• 132 mg NOx/m2 uptake (November-January

in Valencia)

• or 271 µg/ (m2 /h) NOx por m2/h ( sunny

hours)

• 10 times better than experiments at

laboratory scale using artificial sunlight

Figure 1. Concentration of nitrates

obtained, after washing the pieces and by

unit of area. No particles were detected by

the denuder filters or the SMPS, so at all

the nitrate contained in the tiles was

formed through heterogeneous catalytic

reaction on the surface of the impregnated

photocatalytic material and was not

deposited as a photochemical product

particle generated within the chamber

Other highlights

• EUPHORE chambers are one of the best equipped European outdoor photoreactors

for studying atmospheric chemistry, capable of simulating the daily patterns of

total NOx for urban environments and for analyzing the efficiency of the

reduction potential of oxides of nitrogen, and VOCs in the atmosphere of

materials impregnated with a photoactive additive under different typical urban

conditions and/or 24-hour solar cycles.

• Due to its high volume, about 200 m3, a huge surface of material could be installed

inside one of the EUPHORE photochemical chambers ( several m2) where they can

be continuously exposed to controlled atmospheric NOx concentrations, natural

sunlight, as well to humidity and other pollutants. In that sense, EUPHORE facilities

are powerful tools for studying nitrogen-oxides, tropospheric O3, and VOCs

reduction potential of materials impregnated with photoactive additives.
