Abstract

TiO₂ composites with zeolite templated carbon (TiO₂-ZTC) and activated carbon (TiO₂-AC) were prepared and used as the photocatalysts for comparative studies with pure TiO₂. TiO₂-ZTC exhibited the highest rate of methylene blue degradation with a rate approximately 4 and 400 times higher than those of TiO₂-AC and pure TiO₂, respectively. Moreover, the highest catalytic performance of TiO₂-ZTC in gas-phase degradation of acetone was approximately 1.1 and 12.9 times higher than TiO₂-AC and pure TiO₂, respectively. These outstanding performances could be attributed to high surface area, pore volume, and hydrophobic surface properties, leading to improvement in the adsorption properties of organic molecules.
