Development of artificial light-driven water splitting nanodevice using gold nanoparticles and photosystem II

为了开发混合型人工光驱动的水裂解纳米器件，制备了光系统II和20-nm金纳米颗粒的缀合物（PSII-GNP），以及进一步将光系统I结合到PSII-GNP的缀合物（PSI-GNP-PSII）。 所获得的PSII-GNP表现出光诱导的O2释放通过分解水和PSI-GNP-PSII表现出电子转移的能力，从PSII到PSI通过介体。此外，在PSI与3-nm铂纳米颗粒（PSI-PtNP）的缀合物中检测到光诱导的H2释放。

To develop a hybrid-type artificial light-driven water splitting nano-device, the conjugate of photosystem II and a 20-nm gold nano-particle (PSII-GNP), and the conjugate that further combined photosystem I to PSII-GNP (PSI-GNP-PSII) were prepared. The obtained PSII-GNP exhibited light-induced O2 evolution by splitting water and the PSI-GNP-PSII showed the capability of electron transfer from PSII to PSI via a mediator. Furthermore, light-induced H2 evolution was detected in the conjugate of PSI with 3-nm platinum nano-particles (PSI-PtNP).
