Abstract

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 H2 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 6th 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.
