Single-atom Pt-I₃ sites on all-inorganic Cs₂SnI₆ perovskite for efficient photocatalytic hydrogen production.

ABSTRACT: Organic-inorganic lead halide perovskites are a new class of semiconductor materials with great potential in photocatalytic hydrogen production, however, their development is greatly plagued by their low photocatalytic activity, instability of organic component and lead toxicity in particular. Herein, we report an anti-dissolution environmentally friendly Cs₂SnI₆ perovskite anchored with a new class of atomically dispersed Pt-I₃ species (PtSA/Cs₂SnI₆) for achieving the highly efficient photocatalytic hydrogen production in HI aqueous solution at room temperature. Particularly, we discover that Cs₂SnI₆ in PtSA/Cs₂SnI₆ has a greatly enhanced tolerance towards HI aqueous solution, which is very
