Photocatalysis of functionalised 3D printed cementitious materials

“…In the last decades, the increase of environmental pollutants has become one of the major concerns worldwide, since it is directly or indirectly related to population health issues [1][2][3]. Air pollutants, such as ground level ozone, carbon monoxide, and nitrogen oxides (NO x ), among others, released due to the gas emission from the industrial activities and traffic exhausts, may cause several types of illnesses, such as respiratory and lung diseases, which can significantly influence the quality of life of an human beings [4][5][6][7][8]. Moreover, polluted urban areas and soot fouling are two reasons for the life cycle reduction of construction materials that may deteriorate the aesthetic performances of the built environments' surfaces [9,10].…”
