硼氧配阴离子在水溶液中存在电子自震荡现象，这是迄今为止溶液化学中一个极为奇特的事例。我们通过引入具有电子自振荡这一特性的硼氧配阴离子并借助它在电子传递过程中的特殊贡献、反应气氛惰性化、加入电子易给体等方法，有效避免了染料分子的被氧化，大大增强染料敏化半导体催化剂的稳定性，提高了光催化产氢效率。本课题拟通过谱学表征(稳态/瞬态荧光光谱、激光拉曼光谱)及其它光电化学表征技术深入研究如下两个层面的科学问题：1.硼氧配阴离子电子自振荡这一特质在提高电子/空穴对分离、电子有效传递、空穴有效消耗进而增强染料敏化光催化剂稳定性、提高光催化产氢效率的内在作用机制；2.硼氧配阴离子与半导体之间的结合方式、染料与半导体之间通过硼原子的配位键合方式及该结合方式之所以有效的内在原因。在上述认知基础上，探究能提高染料敏化半导体光催化剂稳定性的有效方法，构建稳定、高效的染料敏化半导体可见光诱导还原水制氢反应新体系。

The electron oscillation of borate complex anions in the borate solution was a very interesting peculiar phenomenon in the study of Solution Chemistry up to now. By means of borate complex anions addition, reacting system inertion and the electron donors addition, based on the peculiar contribution of borate complex anions with an electron oscillation characters, the stabilities of dye-sensitized semiconductors were greatly improved and the photocatalytic hydrogen evolution were efficiently enhanced. In this study, the following two scientific problems will be investigated: 1.the particular behavior mechanism of borate complex anion's electron oscillation on the stabilities of dye-sensitized semiconductors and the enhancement of photocatalytic hydrogen evolution. 2. the structure - activity relationships of combination mode between the borate complex anions and the semiconductors, between the dye molecules and the semiconductors through boron coordination bond. Based on the above researches, we hope to probe the effective methods for the improvement of the stabilities of dye-sensitized semiconductors, to construct the new efficiently photocatalytic reduction of water to hydrogen reaction system.
