The addition of MoO[sub 3] to TiO[sub 2] enhanced its photocatalytic properties by 100%. This may be related to an increase in the rate of transfer of electrons from the TiO[sub 2] to the outer system, via the formation of a reduced molybdenum species. Samples of MoO[sub 3]/TiO[sub 2] mixed oxide powders were prepared by two methods: (1) the incipient wetness impregnation of ammonium paramolybdate onto TiO[sub 2] (P25), followed by a heat treatment, and (2) the ultrasonic nebulization and flame hydrolysis of a mixed ethanol solution of molybdenyl acetylacetonate and dipropoxy-titanium-bis(acetylacetonate). The photocatalytic activities of TiO[sub 2] based catalysts were evaluated by the degradation of 1,4-dichlorobenzene (DCB). TiO[sub 2] has promising applications in the treatment of both waste and drinking water.
