    Abstract

    The use of photocatalysts in environmental pollution control may be considered as a clean process. Besides the activity of a photocatalyst, the application of it is also limited by the production cost. In this study, we attempted to prepare high-activity titania photocatalysts through a low cost process. The ball-milled K2Ti4O9 was first treated by a hydrochloric acid followed by a microwave-assisted hydrothermal reaction to prepare TiO2. The prepared titania showed small particle sizes and high specific surface areas. The photocatalytic activities were evaluated by the photo-destruction of NOx gas under the irradiation with different wavelengths. The prepared titania showed high photocatalytic activies similar or even exceeded the commercial one, AEROXIDE® TiO2 P 25.
