Develop a highly active, durable, and cost-effective electrocatalyst for water oxidation to enhance water-splitting systems and rechargeable metal-air batteries.
Synthesized ultrathin nickel-iron layered double hydroxide (NiFe-LDH) nanoplates directly on mildly oxidized multiwalled carbon nanotubes (CNTs).
Evaluated the electrocatalytic activity and stability of the NiFe-LDH/CNT hybrid complex for the oxygen evolution reaction in alkaline media relative to commercial iridium catalysts.
Incorporating iron into nickel hydroxide induced the formation of crystalline NiFe-LDH nanoplates with high intrinsic activity for the oxygen evolution reaction in alkaline solutions.
The NiFe-LDH/CNT complex demonstrated superior electrocatalytic activity and durability for oxygen evolution compared with commercial precious-metal iridium catalysts.
