ADVANTAGES IN REACTION SPEED FOR DECONTAMINATION BY HYDROXIL RADICALS PRODUCED BY PHOTOCATALYSIS OVER DIFFERENT OTHER COMPOUNDS FOR DISINFECTION OF AIR AND SURFACES.

What is the explanation for the efficiency of these techniques? The processes involved have a greater thermodynamic feasibility and a greatly increased oxidation rate due to the participation of radicals, mainly the hydroxyl radical, HO* . This species has adequate properties to attack virtually all organic compounds and react 106 -1012 times faster than alternative oxidants such as O 3 .
