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

Abstract

Abstract 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.
