Self-assembled dye–layered double hydroxide–Pt nanoparticles: a novel H2 evolution system with remarkably enhanced stability
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
