Resumen:
CF3COCl is effectively photooxydized when a gaseous sample interacts with an illuminated TiO2 covered surface.The oxidation occurs irrespective of the presence of O2. The main products are CO2 and CF2O. It was observed that a poisoning of the catalyst occurred after successive runs and a partial recovery when ambient air entered the cell, thus, pointing to water as the responsible for the recovery.
