Behaviour of TiO2-SiMgOx hybrid composites on the solar photocatalytic degradation of polluted air

▶ TiO2-SiMgOx hybrid composites are evaluated for the photodegradation of trichloroethylene in gas phase with a CPC solar reactor. ▶ Combination of an adsorbent and a photocatalyst widens the operating conditions window of the system. ▶ CO2 selectivity is promoted at high solar irradiance conditions. ▶ TiO2-SiMgOx composite allows total TCE degradation at severe operating conditions.
