     the decomposition of gas-phase hexane in air streams by immobilized nanoparticles of tio2 and zno onto perlite and poraver® granules was studied. photocatalytic degradation experiments were conducted in batch and plug flow continuous photoreactors at a uv irradiation of 254 nm. the tio2 and zno samples had similar hexane degradation rates and conversion percentages in batch tests. photolysis contributed to 58% of the photodegradation phenomena. the hexane batch degradation velocities that normalized to impregnated support mass were similar for both semiconductors. when normalized to abet of the impregnated support, zno allowed a higher hexane degradation velocity than tio2. maximal mineralization of hexane in batch tests was 98% and 57% for tio2 and zno sytems, respectively.
