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.
制备了具有沸石模板碳的二氧化钛复合材料（TiO2-ZTC）和活性炭复合材料（TiO2-AC），并将其用作光催化剂，与纯TiO2进行对比研究。TiO2-ZTC表现出最高的亚甲基蓝降解速率，其速率分别比TiO2-AC和纯TiO2高约4倍和400倍。此外，TiO2-ZTC在丙酮气相降解中的最高催化性能分别比TiO2-AC和纯TiO2高约1.1倍和12.9倍。这些优异的性能可归因于高表面积、孔体积和疏水表面性质，从而改善了有机分子的吸附性能。
