Interface Engineering of Co-LDH@MOF Heterojunction in Highly Stable and Efficient Oxygen Evolution Reaction.

Abstract in brief

• The study focuses on improving the efficiency of water splitting for clean energy by engineering heterojunctions between ZIF67 and layered double hydroxide (CoLDH), which enhances both catalytic activity and stability during oxygen evolution reaction (OER).
• The interface between CoLDH and ZIF67 is formed through interactions between oxygen in CoLDH and nitrogen in ZIF67's ligand, which modifies the electronic structure of active sites, making it easier to break chemical bonds involved in OER.
• Experimental and theoretical results show that this engineered heterojunction significantly lowers the energy barrier for OER, achieving high activity with low overpotential and sustaining stability for over 50 hours, offering a promising approach to optimize catalytic performance for water splitting.]
