摘要：
We report the first accessible channel-like open pore architecture of ordered 2D hexagonal mesoporous IrO2 films and its utilization as an efficient anode for electrocatalytic water oxidation. A well-ordered mesostructure of circa 7nm pores were obtained by a facile one-pot soft-templating strategy, employing a [Ir(OH)(6)](2-) precursor stabilized by a triblock copolymer PluronicF127 as a pore-directing template. A mesoporous IrO2 film calcined at 400 degrees C (approximate to 70nm thick) affords a high surface area of 512m(2)cm(-3) and 2times higher O-2 evolution during the electrocatalytic water oxidation relative to an untemplated IrO2 coating film.
