Modulating the covalency of Ru-O bonds by dynamic reconstruction for efficient acidic oxygen evolution.

ABSTRACT: Developing ruthenium-based oxide catalysts capable of suppressing lattice oxygen participation in the catalytic reaction process is crucial for maintaining stable oxygen evolution reaction (OER) under acidic conditions. Herein, we delicately construct a RuO₂ nanoparticle-anchored LiCoO₂ nanosheet electrocatalyst (RuO₂/LiCoO₂), achieving dynamic optimization of RuO₂ during the reaction process and improving catalytic stability. Benefiting from the unique electrochemical delithiation characteristics of the LiCoO₂ support, the covalency of the Ru-O bond is effectively regulated during the OER process. The weakened Ru-O covalent bond inhibits the participation of lattice oxygen in the catalytic reaction and ensures the continuou
