中文摘要：

Nitro 芳香的混合物能 photocatalytically 被简化为在 UV/TiO2/holes scavenger 和 Vis/TiO2/dye-sensitized 系统把 TiO2 用作光催化剂的相应胺芳香的混合物。在 UV/TiO2/holes scavenger 系统，象甲醇那样的反应底层白酒能被用作洞 scavengers，并且在 Vis/TiO2/dye-sensitized 系统，底层白酒能与高选择被氧化到相应的醛。当甲醇被用作洞 scavengers，照明时间是 6 h 时， 87.2%p 硝基甲苯能 photocatalytically 被简化为 p-toluidine。在 Vis/TiO2/dye-sensitized 系统，为硝基苯的 photocatalytic 减小的芳香的白酒的效果比另外的白酒的好。同时，芳香的白酒能容易被氧化，并且相应的醛的生产效率比另外的白酒的那些高。可能的反应机制也被建议。

英文摘要：

Nitro-aromatic compounds can be photocatalytically reduced into the corresponding amine-aromatic com- pounds using TiO2 as a photocatalyst in the UV/TiO2/holes scavenger and Vis/TiO2/dye-sensitized systems. In the UV/TiO2/holes scavenger system, reaction substrate alcohols such as methanol could be used as the holes scavengers, and in the Vis/TiO2/dye-sensitized system, substrate alcohols could be oxidized to the corresponding aldehydes with high selectivity. When methanol was used as the holes scavengers and the illumination time was 6 h, 87.2% ofp-nitrotoluene could be photocatalytically reduced into p-toluidine. In the Vis/TiO2/dye-sensitized system, the effect of aromatic alcohols for the photocatalytic reduction of nitrobenzene was better than that of other alcohols At the same time, aromatic alcohols can be easily oxidized, and the production efficiencies of the corresponding aldehydes were higher than those of other alcohols. The possible reaction mechanisms were also proposed.
