Cultivating crystal lattice distortion in IrO2via coupling with MnO2 to boost the oxygen evolution reaction with high intrinsic activity

Here, we report an effective strategy to lower Ir consumption and boost the OER performance in acid by loading IrO2 onto MnO2, in which the IrO2 crystals are well dispersed and undergo a so-called z-extension Jahn–Teller distortion in the octahedral structure. Compared with IrO2, the mass activity a...

Summary:Here, we report an effective strategy to lower Ir consumption and boost the OER performance in acid by loading IrO2 onto MnO2, in which the IrO2 crystals are well dispersed and undergo a so-called z-extension Jahn–Teller distortion in the octahedral structure. Compared with IrO2, the mass activity and intrinsic activity for IrO2/MnO2 were largely increased.
