Abstract:The report presents two main parts, which are fabrication of TiO2 layer on microchanel silicon substrate and characterization of photocatalytic performance of TiO2 layer. The catalyst deposition on the substrate was conducted by using washcoating techniques. The morphology of catalyst layer obtained was analyzed by using SEM. The adhesion test was conducted to observe the adherence of catalyst layer to the substrate. SEM was used to observe the difference of catalyst layer between before and after adhesion test. The photocatalytic performance of catalyst layers was investigated by determining the intrinsic surface reaction rate constant. In order to determine the intrinsic surface reaction rate constant the results from numerical simulation were fitted to experimental data obtained for various residence times, substrate types and pH solution.
