High-entropy perovskite fluorides (HEPFs) have great potential in electrocatalysis that has not been realized because of the limitation of a high-temperature synthetic route and the limited understanding of high-entropy materials. The use of HEPFs in effective oxygen evolution catalysis and a feasible synthesis route for HEPFs in a boiled solution by combining a hydrothermal method with mechanochemistry are first reported here. These HEPFs consisting of cost-effective elements dramatically gave excellent catalytic activity for the oxygen evolution reaction in an alkaline media.
高熵钙钛矿氟化物（HEPFs）在电催化领域具有巨大潜力，但由于高温合成路线的限制以及对高熵材料的了解有限，这种潜力尚未得到充分发挥。本文首次报道了HEPFs在有效析氧催化中的应用，以及通过水热法与机械化学相结合在沸腾溶液中合成HEPFs的可行路线。这些由具有成本效益的元素组成的HEPFs在碱性介质中对析氧反应具有显著的优异催化活性。
