Abstract

Atmospheric pollution is the main environmental and health hazard in several countries, and the World Health Assembly approved the WHA68.8 resolution in which were PM10, PM2.5, NO2, O3, and SO2 are identified as the main regulated atmospheric pollutants. Thus, the present paper characterizes the photocatalytic reaction efficiency of two polymeric solutions (used as vinylic and waterproofing paint) that have TiO2 as photocatalytic active when being exposed to different CO2 sources. Using an Air Pollution Monitor for measuring NOx, SOx, and CO2, the decreasing of this pollutant was proved. In addition, SEM (Scanning Electron Microscopy) was used for measuring the adherence quality of the paint to the substrate and the changes in the surfaces where the solutions were applied. It was found the conversion velocity was greater when the CO2 was emitted by a vehicle than when coming from a polymer combustion.
