Earth-abundant oxygen evolution catalysts (OECs) with extended stability in acid can be constructed by embedding active sites within an acid-stable metal-oxide framework. Here, we report stable NiPbO<sub>x</sub> films that are able to perform oxygen evolution reaction (OER) catalysis for extended periods of operation (>20 h) in acidic solutions of pH 2.5; conversely, native NiO<sub>x</sub> catalyst films dissolve immediately. In situ X-ray absorption spectroscopy and ex situ X-ray photoelectron ...[more]
