| Abstract: | The distribution of the intermediates and products produced in the heterogeneous photocatalytic degradation of benzene over TiO_2 and Pt/TiO_2 was investigated by GC and in-situ FTIR methods. The results suggested that the platinized TiO_2 was favor the degradation of the intermediates, leading to the improvement of the performance of the photocatalytic reaction. |
