The photocatalytic efficiency of TiO2 immobilised on various supports (glass, cement, red brick and inorganic fibres), using different techniques (sputtering, sol-gel dip-coating, patented method for inorganic fibres), are compared with the photocatalytic efficiency of TiO2 Degussa P25 in suspension 2 g l(-1), for the degradation of 3-nitrobenzenesulfonic acid (3-NBSA) and 4-nitrotoluenesulfonic acid (4-NTSA). In all cases, the fixation of TiO2 on solid supports appreciably reduces the photocatalytic efficiency. The best results were obtained with TiO2 on inorganic fibres.
