Accelerating the Electrocatalytic Performance of NiFe–LDH via Sn Doping toward the Water Oxidation Reaction under Alkaline Condition

, which is almost five times higher than that of bare NiFe-LDH. This study highlights Sn doping as an effective strategy for the development of low-cost, effective, stable, self-supported electrocatalysts with a high current density for improved OER and other catalytic applications in the near future.
