Synergistic Geometric and Electronic Modulation in Ni–Ce Layered Double Hydroxides for Enhanced Oxygen Evolution Reaction

Key Points

• To investigate the effects of cerium doping on oxygen evolution catalysts for water electrolysis.
• Controlled doping of cerium in nickel-based layered double hydroxides (Ni1-xCex–LDHs) was performed.
• Catalytic activity was assessed for the oxygen evolution reaction under various conditions.
• Cerium doping was found to enhance the performance and durability of catalysts.
• Significant improvements in the efficiency of oxygen evolution reaction were observed.
