As human beings spend the majority of their time indoors, good indoor air quality standards should be guaranteed worldwide. However, poor indoor air causes several adverse health effects and thus should be treated as a global interest. Photocatalysis might be a partial response to such a concern. To this aim, we have synthesised, by means of a green, clean, and simple sol-gel method, titania modified with copper oxide(s) and graphene hybrid nanomaterials. Photocatalytic activity of as-prepared materials was tested against two class of pollutants commonly found indoor: benzene as model volatile organic compound, and nitrogen oxides. A white-light LED bulb commonly found inside households was employed as the light source.
