Facile synthesis of nanometer-sized NiFe layered double hydroxide/nitrogen-doped graphite foam hybrids for enhanced electrocatalytic oxygen evolution reactions

N-doped graphite foam (NGF) effectively improves the anchoring and dispersing of NiFe layered double hydroxide (NiFe LDH), providing the free-standing NiFe LDH/NGF electrode with superior performance in water oxidation.296
