Creation and Kinetics Analysis of Biocatalysis-Electrode Interface for Energy Conversion

生物燃料电池作为一种强有力的能量转换系统，其基础研究和应用研究是未来发展的方向。以酶或微生物为催化剂的直接电子转移（DET）型生物电催化反应为研究对象，详细讨论了电子转移机理和酶在电双层中的稳定性。另一方面，提出了适合于酶固定和DET反应的介孔碳材料和生物电极的制备方法。在此基础上，成功地构建了一种新型的生物阴极，在无源模式下，其稳态电流密度高达20mA cm^<-2>。演出是世界上最好的。

Fundamental and applied researches have been performed for biological fuel cell as a potent energy conversion system in future. By focusing on direct electron transfer (DET) type bioelectrocatalytic reactions with enzymes or microbes as catalysts, mechanism of the electron transfer and stability of enzyme in electric double layer have been discussed in detail. On the other hand, methods for preparation of mesoporous carbon material suitable for enzyme immobilization and DET reactions and of bio-electrodes have been presented. Based on these studies, a novel biocathode to show a steady-state current density as high as 20mA cm^<-2> under passive mode, has successfully been constructed. The performance is the best in the world.
