采用水热法制备了α-MnO 2/MIL-101（Cr）复合催化剂。在该复合材料中，α-MnO 2纳米颗粒嵌入到具有丰富微孔和高比表面积的MIL-101（Cr）基体中，提高了反应物对催化活性位点的可及性，从而显著改善了碱性电解液中的氧还原反应（ORR）和析氧反应（OER）。α-MnO 2纳米粒子与MIL-101（Cr）基体之间的强相互作用导致了高的结构稳定性，从而具有优异的活性稳定性。
An α-MnO2/MIL-101(Cr) composite catalyst was synthesised using a hydrothermal process. In this composite, α-MnO2nanoparticles are embedded in an MIL-101(Cr) matrix with abundant micropores and a high specific surface area, which improves the reactant's accessibility to catalytically active sites, resulting in a significant improvement in oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in an alkaline electrolyte. The strong interactions between α-MnO2nanoparticles and MIL-101(Cr) matrix result in a high structural stability and therefore excellent activity stability.
