10"6 and 1.4 X 10-4 M. None of these runs gave good first-order or second-order plots, and we therefore obtained the order of the reaction in naphthalene by analyzing the initial rates ( ) as shown in Figure 2. By this method the order in napthalene was determined to be 1.5. This surprising result was verified by reexamination of the full kinetic runs, which were found to fit plots for a reaction 1.5 order in naphthalene. These results are in contrast to those of Ridd and Co-workers,4 who found N(EI)-catalyzed nitration of N^V-dimethylaniline to be first order in the aromatic. This finding is moreover obviously not in accord (7)

Fe-doped TiO2(Fe/TiO2) film photocatalyst was prepared by sol-gel and dip-coating process to extend its photoresponsivity to the visible spectrum. To promote the CO2reduction performance with the photocatalyst, some types of base materials used for coating Fe/TiO2, which were netlike glass fiber and Cu disc, were investigated. The characterization of prepared Fe/TiO2film coated on netlike glass fiber and Cu disc was analyzed by SEM and EPMA. In addition, the CO2reduction performance of Fe/TiO2film coated on netlike glass disc, Cu disc, and their overlap was tested under a Xe lamp with or without ultraviolet (UV) light, respectively. The results show that the concentration of produced CO increases by Fe doping irrespective of base material used under the illumination condition with UV light as well as that without UV light. Since the electron transfer between two overlapped photocatalysts is promoted, the peak concentration of CO for the Fe/TiO2double overlapping is approximately 1.5 times as large as the Fe/TiO2single overlapping under the illumination condition with UV light, while the promotion ratio is approximately 1.1 times under that without UV light.
