Ruthenium clusters decorated on lattice expanded hematite Fe₂O₃ for efficient electrocatalytic alkaline water splitting.

ABSTRACT: Electrocatalytic water splitting in alkaline media plays an important role in hydrogen production technology. Normally, the catalytic activity of commonly used transition metal oxides usually suffers from unsatisfactory electron conductivity and unfavorable binding strength for transition intermediates. To boost the intrinsic catalytic activity, we propose a rational strategy to construct lattice distorted transition metal oxides decorated with noble-metal nanoclusters. This strategy is verified by loading ruthenium clusters onto lithium ion intercalated hematite Fe₂O₃, which leads to significant distortion of the FeO₆ unit cells. A remarkable overpotential of 21 mV with a Tafel slope of 39.8 mV dec^-1 is achieved at 10 mA cm^-2 for the
