The photocatalytic decomposition and mineralization of 4-chlorophenol (4-CP), hydroquinone and 4-nitrophenol (4-NP) in aqueous solution were investigated using two kinds of low-pressure mercury lamps: one was UV (ultraviolet) lamp emitting at 254nm and the other was VUV (vacuum ultraviolet) lamp emitting at both 254 and 185nm. VUV irradiation led to the most efficient degradation of the organics....
The photocatalytic activity of the carbon-black-modified nano-TiO 2 (CB-TiO 2 ) thin films was 1.5 times higher than that of TiO 2 thin films in degrading Reactive Brilliant Red X-3B. Photocatalytic oxidation and ozonation of catechol over CB-TiO 2 thin films supported on Al sheet was investigated. The experiments showed that ozone concentrations had an important effect...
