光敏蛋白人工复合膜的能量转换与电子传递研究

The studies of the photoinduced and electric-field-driven ET processes and energy converting are very important for revealing the mechanism of electron transfer and energy transfer and building up a mimic photoelectric element on the molecular level. The studies for Rb. Sphaeroides, especially for the ET processes in RC, are more attractive and hundreds of papers are published every year. However, most of the studies on the photoelectric processes are performed by the spectral and biological methods and are indirect. Moreover, many problems associated with the photoelectric reaction parameters and the ET mechanism are still unsolved. In this project, the investigations surrounding RC were carried out with the electrochemical and photoelectrochemical methods, and a series of the innovative results were obtained. This research was of great significance for further understanding the ET processes and the photoelectric conversion mechanism in RC, fabricating the mimic biophotoelectric element and optimizing the performance of the biophotoelectric element.
