Article Synopsis
- The study focuses on creating effective and affordable electrocatalysts for water electrolysis, vital for improving technology in this area.
- The authors developed a novel catalyst by anchoring carbonyl iron powder in nickel foam, leading to enhanced surface area and efficient ion movement.
- The catalyst exhibits high activity due to a dynamic interaction between different nickel and iron phases, significantly boosting its performance in the oxygen evolution reaction.
For sustained hydrogen generation from seawater electrolysis, an efficient and specialized catalyst must be designed to cope with the slow anode reaction and chloride ions (Cl) corrosion. In this work, an S-modified NiFe-phosphate with hierarchical and hollow microspheres was grown on the NiFe foam skeleton (S-NiFe-Pi/NFF), acting as a bifunctional catalyst to enable industrial-scale seawater electrolysis. The introduction of S distorted the lattice of NiFe-phosphate and regulated the local electronic environment around Ni/Fe active metal, both of which enhanced the electrocatalytic activity.
