Summary: By regulating the atomic environment of high-entropy-alloy (HEA) electrocatalysts, inactive sites can be transformed into active sites, leading to enhanced catalytic activity. A high-entropy FeCoNiCuMn HEA nanoparticle was synthesized by integrating low-electronegativity Mn and high-electronegativity Cu with Fe, Co, and Ni base metals, which facilitated the transformation of inactive Cu to electron-enriched active sites. This resulted in reduced adsorption energies of reactants, intermediates, and products, leading to improved hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) activity. The HEA exhibited superior electrocatalytic activity and cycling stability, surpassing Pt/C and IrO2 catalysts. This work represents a breakthrough in the design of advanced HEA electrocatalysts for complex reactions.

Summary: Tuning the electronic structure of the active centers in covalent organic frameworks (COFs) is crucial for balancing the adsorption ability and reactivity of oxygen in the 2e(-) oxygen reduction reaction (ORR) for electrocatalytic synthesis of hydrogen peroxide (H2O2). By introducing different by-design building blocks, the adsorption ability of oxygen molecule (O-2) can be finely tuned, and the binding strength of O-2 is positively correlated with the electron-donating ability of the active center. The newly designed TP-TD-COF exhibits higher 2e(-) ORR activity and selectivity due to its stronger electron-donating ability and higher adsorption strength of O-2 on the electron-rich active center. This work reveals the fundamental structure-activity relationship in H2O2 synthesis and provides a strategy for designing metal-free COF catalysts through rational modulation of their electronic properties at the molecular level.
