Octahedral Tantalum Bromide Clusters as Catalysts for Light-Driven Hydrogen Evolution.

ABSTRACT: The development of an efficient hydrogen generation strategy from aqueous protons using sunlight is a current challenge aimed at the production of low-cost, easily accessible, renewable molecular hydrogen. For achieving this goal, non-noble metal containing and highly active catalysts for the hydrogen evolution reaction (HER) are desirable. Octahedral tantalum halide clusters {Ta₆(μ-X)₁₂}²⁺ (X = halogen) represent an emerging class of such HER photocatalysts. In this work, the photocatalytic properties of octahedral aqua tantalum bromide clusters toward HER and in acid and homogeneous aqueous conditions were investigated. The [{Ta₆Brⁱ₁₂}Br^a₂(H₂O)^a₄]·4H₂O (i =
