摘要：
Supercritically treated TiO2-activated carbon (Sc-TiO2-AC) composites were studied for their adsorption and photocatalytic activities toward gaseous ammonia (NH3). The experiments were carried out at 26 degrees C using a black lamp. The Sc-TiO2-AC composites attained higher photocatalytic activities than supercritically treated TiO2 (Sc-TiO2). NH3 was found out to be converted by the Sc-TiO2-AC composites to compounds such as N-2, N2O, NO2- and NO3-. The main product was harmless N-2. The Sc-TiO2-AC composites are expected to be applied as effective cleaning materials to environments that emit offensive NH3 odors.
