摘要

•A high-entropy perovskite La(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3-δ (LCMFCN) was synthesized.•LCMFCN showed a better catalytic activity and stability for PMS activation.•Non-radical 1O2 played a vital role in RhB degradation in the PMS/LCMFCN system.•Oxygen vacancy and the cations in B-site might promote PMS activation.
