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 photocatalysts, however, instability and toxicity pose challenges. Here, the authors report a non-toxic all-inorganic Cs2SnI6 perovskite anchored with atomically dispersed Pt-I3 for efficient photocatalytic hydrogen production in hydrogen iodide solution.
