VOCs Removal by Oxidation/Reduction Reaction of Cu-Doped Photocatalyst

K. W. Nam, H. R. Jeong, and S. H. Ahn
Abstract—Photocatalytic TiO2 is widely used in many devices and applications in our lives and its usefulness has been significantly evaluated. Nevertheless, as has been demonstrated, TiO2 has low efficiency as it only reacts in the UV-A region. In order to address this problem, this study attempted to develop photocatalytic materials that can be used in many situations by doping a relatively low energy gap. The photoactive and the photocatalyst characteristics were evaluated to develop a photocatalyst. The photoactive characteristic was analyzed with the FT/IR using TCE. While pure TiO2 showed photoactivity only in the UV-A region, Cu/TiO2 showed photoactivity in both the UV region and the visible region. Unlike pure TiO2, dichloroacetyl choride (DCAC) was not found on the detected reaction product with Cu/TiO2 photocatalytic reaction. At oxidation, the degradation of TiO2 was greater than that of Cu/TiO2. However, the degradation of Cu/TiO2 was greater than that of TiO2at reduction.

Index Terms—Cu-doped photocatalyst, oxidation/reduction, volatile organic compounds (VOCs).
