| 제목 | Effect of Al2O3 interlayer on the redox reactions with photocharged TiO2 and WO3 filters |
| 초록 | In the absence of irradiation, the pre-photo charged binary TiO2 and WO3 membrane filters apply to redox reactions of heavy metal ions (Cr(VI) and As(III)). When Al2O3 is inserted between TiO2 and WO3, it enables more charged electrons to transfer to WO3 while blocking back electrons from transferring to TiO2. As a result, when TW is replaced with TAW, direct electron transfer enhances Cr(VI) reduction. With the charged TAW, however, As(III) oxidation mediated by the O2 reduction reaction is retarded. This study indicates the effect of Al2O3 on direct vs. mediated electron transfer via heavy metal ion redox reactions. |
