Boosting Oxygen Evolution Reaction by Bulk-Confined Zn Doping in NiFe-LDH Anchored on Stainless Steel Foam

Key Points

• The aim is to enhance the kinetics of the oxygen evolution reaction (OER) through bulk Zn doping in NiFe-LDH.
• Designed a hierarchical Zn@NiFe-LDH catalyst
• Confined Zn to the bulk to prevent site blocking
• Anchored catalyst on stainless steel foam
• Significant enhancement in OER kinetics observed
• Bulk Zn doping electronically modulated the active sites
