摘　　要：Titanium dioxide （TiO2） is widely employed as a solid photocatalyst for solar energy conversion and envi- ronmental remediation. The ability to construct porous TiO2 with controlled particle size and narrowed bandgap is an essential requirement for the design of highly efficient and recyclable photocatalysts. Here, we report a template- free acetic acid induced method for the synthesis of visible- light responsive carbon-doped TiO2 microplates with high crystallinity and mesoporous structure. It is shown that the electron-withdrawing bidentate carboxylate ligands derived from acetic acid can narrow the bandgap of TiO2 （1.84 eV） substantially. Moreover, the resultant microplate photo- catalysts exhibit excellent photocatalytic efficiency and solid-liquid separation performance, which will be bene- ficial for future industrial applications.钛二氧化物(TiO ₂) 广泛地为太阳能变换和环境补习作为稳固的光催化剂被采用。与控制粒子尺寸和缩小的 bandgap 构造多孔的 TiO ₂ 的能力是为设计的一个必要要求高度有效并且 recyclable 光催化剂。这里，我们报导没有模板的醋酸与高 crystallinity 和 mesoporous 结构为可见光的应答的做碳的 TiO ₂ microplates 的合成导致了方法。从醋酸导出的撤退电子的有二齿的羧化物 ligands 能缩小 TiO ₂ 的 bandgap，这被显示出(1.84 ? eV ) 实质地。而且，结果的 microplate 光催化剂展出优秀 photocatalytic 效率和稳固液体的分离性能，它将为未来是有益的工业应用。
