- Interfacial Synergy in CeO 2 ‐Decorated MgAl‐LDH Heterostructures for Enhanced Oxygen Evolution Reaction Rashida Yahya Abdul Majid Khan Mingmin Cao Biao Li Yibu Dou Yunning Chen Jingbin Han ChemSusChem Designing efficient, durable, and cost‐effective electrocatalysts for the oxygen evolution reaction (OER) remains a critical challenge in the development of advanced water‐splitting technologies. Herein, a series of CeO 2 ‐decorated MgAl‐layered double hydroxide (LDH) heterostructures were rationally synthesized via a facile hydrothermal approach. Structural and morphological characterizations confirm the successful integration of CeO 2 nanoparticles onto the LDH nanosheets without compromising the layered architecture. Among the synthesized catalysts, the C‐5L heterostructure exhibits superior OER performance in 1 M KOH, requiring an onset potential of 0.28 V and overpotential of only 0.32 V to deliver a current density of 10 mA cm −2 , significantly lower than its undoped and higher doped counterparts. The optimized catalyst also achieves the smallest Tafel slope (80 mV dec −1 ), the lowest charge‐transfer resistance (34 Ω), and the highest C dl (4.21 mF cm −2 ), indicating enhanced reaction kinetics and increased electrochemically active surface area. Furthermore, it demonstrates the highest mass activity (28 A g −1 at 0.37 V vs. RHE) and exceptional operational stability over 100 h at 100 mA cm −2 . This study underscores the theme of interfacial engineering between CeO 2 and LDH, providing valuable insights into designing high‐performance OER catalysts through controlled electronic coupling and defect modulation. 10.1002/cssc.70764 http://onlinelibrary.wiley.com/termsAndConditions#vor
