摘要：

A novel photocatalytic hydrogen evolution system was constructed by using well-dispersed layered double hydroxide (LDH) to immobilize the photosensitizer (rose bengal, RB) and photocatalyst (Pt). The produced amount of H-2 from such a self-assembled RB-LDH-Pt system is a few times more than that from the Free system (without LDH). Moreover, RB-LDH-Pt can be reused for at least 6 times (still having 64% of the activity in the 6(th) run) by a simple method of centrifugation which makes this system more economical by recycling the expensive Pt. The total turnover number (TON) obtained after six runs for RB-LDH-Pt was calculated to be 304 based on Pt, which gave at least 13-fold enhancement compared with that from the Free system.
