The electrolysis of water requires excess energy in the form overpotential to overcome activation barriers due sluggish kinetics both hydrogen evolution reaction (HER) and oxygen (OER). As an inexpensive bifunctional catalyst with noble-metal-like electrocatalytic properties, two-dimensional layered double hydroxides (LDHs) have received considerable attention. Here, a simple electrodeposition method is proposed synthesize La-doped NiFe LDH (NiFeLa LDH) on nickel foam. NiFeLa exhibits excellent splitting performance synergistic effect La laminate metal, best 399 mV for OER 223 HER at current density 50 mA cm–2, along durability alkaline solution tests 24 h. electrochemical analysis other characterization results confirm that doping can change electronic structure laminates. According functional theory calculations, remarkably enhanced catalytic ascribed decrease adsorbed adsorption hydroxide, making transformation from *OH *O rate-determining step process four-electron mechanism. Additionally, electrolyzer as anode cathode provides good stability well reduced cell voltage 1.921 V provide cm–2. Overall, this study offers simple, convenient, rapid, environmentally friendly fabricating high-performance catalysts.
