The FOTOFREC project aims to address two disparate challenges such as the reduction of air pollution and the attenuation of radio frequency communications signals, through the research and development of innovative antipolution, photocatalytic glazing, which have selective frequency surfaces. At present the essential constituent material of glazing is calcium sodium glass, which has great visible transparency and high chemical and environmental stability. However, it presents a number of drawbacks. Some of them, such as energy insulation, sound insulation, and mechanical resistance have been resolved to a greater or lesser extent using double glazing configurations, solar control and underemisive coatings, coatings with certain polymeric materials, tempering processes, and using laminated glass configurations. However, railway windows still have drawbacks such as the attenuation of radio frequency communications signals. This problem is very present in the railway sector, where all windows have solar control and underemisive coatings, which directly influence causing the reduction of mobile phone coverage or the speed of internet connection. To solve this problem we propose the development of prototypes of selective frequency surfaces (FSS) on architectural and transport glass. By properly defining a periodic pattern on that metal layer, structures that allow the passage of a specific frequency range will be achieved. Visual and functional conditions of the final glass resulting from the removal of part of the conductive layer will also be studied in this project, namely: (1) the design of selective surfaces in frequency on glass, (2) the design of selective surfaces in frequency with high thermal efficiency, (3) the design of selective surfaces in frequency with low visual impact, (4) the development of a pre-commercial product that meets the technical requirements of radio frequency signal transmission and solar control simultaneously. In addition, a portable system of spectral measurement of transmission and reflection for glass will be developed to be used in the factory and in whatever the situation of the glass, even if it is already installed, that allows to verify the condition of the layers deposited in the glass and control its degradation over time. On the other hand, in terms of the environment, air pollution is a problem of global interest that causes serious damage to people’s health and the ecosystem. The European Environment Agency (EEA) qualifies the following pollutants as the most harmful and abundant: nitrogen oxides (NOx), tropospheric ozone (O3) and particulate matter (PM). NOx are classified as primary because they are directly generated in anthropogenic activities such as industrial processes and combustion emissions from road traffic. O3 and particulate matter are called secondary pollutants, as these are formed in radical reactions from volatile organic compounds (VOCs), NOx, sulfur derivatives (SOx, H2S), or carbon monoxide (CO). To contribute to the reduction of air pollution, it is intended to design glass with photocatalytic activity that helps to eliminate the most harmful gaseous pollutants using solar energy and water, focusing initially on nitrogen oxides (NOx). There is currently no glass on the market that has the ability to remove pollutants from the air. For the development of glass of this type it will be necessary in the first place the improvement of the experimental system and its adaptation to the methods of measurement of the pollutants that are desired.
