| Outline of Final Research Achievements |
In this work, solid acid-TiO2 composites and TiO2 coated porous glass fiber clothes were prepared for effective adsorption and photocatalytic decomposition of ammonia in air environment. The solid acid-TiO2 composites were adsorbed ammonia effectively. However more NO3-, a product of ammonia decomposition, was detected from the non-treatment TiO2 compared with acid-TiO2 composites. It is indicated that the solid acid-TiO2 composite is not effective to enhance the photocatalytic decomposition of ammonia. TiO2 coated porous glass fiber clothes were prepared by acid treatment of E-glass fiber clothes and subsequent dip-coating of TiO2. The TiO2-coated porous glass fiber clothes exhibited higher adsorption capabilities and high photocatalytic decomposition activities against 2-propanol than TiO2-coated nonporous glass fiver clothes.
