The methods most commonly utilized for deposition of TiO2 on supports are sputtering and sol-gel dip-coating or spin-coating. Generally the fixation of TiO2 on strong supports lowers its performance because of to numerous explanations such as reduction on the active area, a more difficult Trade with Alternative, introduction of ionic species etc. A diploma of 60–70% reduction in performance is reported in aqueous systems for immobilized TiO2 in comparison with the unsupported catalyst (Gaya and Abdullah, 2008), the most beneficial success staying obtained by the immobilization of TiO2 on glass fiber (Rachel et al.
