Preparation of TiO₂ thin layer on ceramics using dip coating method for degradation humic acid

TiO₂ thin layer on ceramic with dip coating method and photocatalyst activity test in humic acid. One of the photocatalysts used for the degradation of humic acid is TiO₂ because TiO₂ has several advantages, including non-toxic, stable, high activity, relatively inexpensive and environmentally friendly. This study was performed using TTIP as a precursor and MEA as an additive in isopropanol. Addition of MEA influences the stability of the titanium oxane solution. Ceramics were coated in a 0.5 M TiO₂ solution by a dip coating method, then dried in an oven at 110°C for 10 minutes and difugeice at 400 ° C for 2 hours. Maximum degradation of 0.5 M TiO₂ is 59.94% over 24 hours using 8 watt fluorescent lamps with 4 TiO₂ coatings on ceramic.
