Morphology Engineering Derived CoOOH With Tunable Oxygen Vacancies for Potential‐Dependent Selective Electrooxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Through a morphology engineering strategy applied to CoFe PBA precursors, we successfully fabricated the CoOOH active phase enriched with oxygen vacancies and abundant edge sites. The introduced oxygen vacancies not only enhance the strong adsorption capacity for oxygen‐containing substrates but also suppress the overoxidation of HMFCA, thus enabling ...
