Photoactive and hydrophobic titanium dioxide-silica coatings on aluminium metal surfaces have been developed by dip-coating of a mixed sol-gel precursor of titanium isopropoxide (TIP) and methyl trimethoxysilane (MTMS). The coating composition of titania-0.5 wt% silica (T-S-0.5), annealed at 400 degrees C in air, effectively degraded 94% and 86% methylene blue after 3 h irradiation under UV and sunlight respectively. A water contact angle of 137 degrees was measured on coated surfaces.
