硼酸盐络阴离子在硼酸盐溶液中的电子振荡是迄今为止溶液化学研究中一个非常有趣的奇特现象。通过硼酸盐络阴离子加成、反应体系惰化和电子加成等方法，利用具有电子振荡特性的硼酸盐络阴离子的特殊贡献，极大地提高了修饰石墨烯的稳定性和析氢性能。这里，光催化活性依赖于硼酸络阴离子与石墨烯的协同作用。研究了硼酸络阴离子与锌钴酸锌修饰的石墨烯之间的构效关系。硼酸盐络阴离子不仅有助于从被激发的曙红染料中更有效地捕获电子，而且有助于更有效地将电子转移到修饰的催化剂上。因此，荧光研究表明，在硼酸盐络阴离子加成的条件下，电荷分离和电子转移更为有效。硼与石墨素之间的协同效应是由于电子转移协同效应的双途径所致。(C)2015爱思唯尔有限公司。保留所有权利。
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 electrons addition, based on the peculiar contribution of borate complex anions with an electron oscillation characters, the stabilities and the hydrogen evolutions of ZnxCo3-xO4 decorated graphene were greatly improved. Here, the photocatalytic activity was dependent on the synergetic effects of borate complex anions and graphene. The structure-activity relationships between the borate complex anions and the ZnxCo3-xO4 decorated grapheme were investigated. The borate complex anions can not only contribute to the more efficiently capture electrons from excited Eosin dye but also beneficial to the more efficiently transfer electrons to the decorated catalysts. So the charge separation and the electrons transfer were more efficient in the condition of the borate complex anions addition as supported by fluorescence studies. The synergetic effects between boron and grapheme were due to the double-pathway of synergetic effects for electrons transfer. (C) 2015 Elsevier Ltd. All rights reserved.
