Volatile organic compounds removal from vehicle interior based on photocatalytic solution

The article presents results of research work which aim was development of solution for volatile organic compounds (VOCs) removal from vehicle indoor air. VOCs, especially benzene, toluene, and xylene (BTX), are air pollutants responsible for many civilizational diseases because of its carcinogenic and mutagenic properties. Concentration of those substances can be even few times higher in micro atmosphere of vehicle cabin than in other indoor atmospheres [1]. The aim of the scientific cooperation between Dr. Schneider Automotive Polska and the Wroclaw University of Science and Technology (WUST) is research on innovative (international range), product development – photocatalytic reactor characterized by Volatile Organic Compounds, especially BTX removal properties. The BTX reduction effectiveness, caused by photocatalytic reactor application in vehicle ventilation system, was subjected to in-depth analysis. The results showed difference on not only maximal benzene, toluene, and xylene reduction (separately) but also in the pattern of response surface. In some tested parameters, the hazardous compounds (as a BTX sum) were reduced for almost 70%. The photocatalytic reactor seems to be prospective solution for air quality improvement in any vehicle cabin.
