The sluggish kinetics of the oxygen evolution reaction (OER) is a key resistance limiting efficiency related technologies. CoFe-based compounds, mainly alloys and oxides, are recognized as effective OER catalysts, with amorphous metal oxides displaying unique properties. catalytic activity catalyst intricately linked to its surface reactivity. However, efforts construct composites interfaces between further enhance activities have progressed relatively slowly. In this work, composite catalyst, denoted Ag/CoFe/Fe2O3/NC, was fabricated by incorporating Ag into crystalline CoFe@amorphous Fe2O3 particles wrapped in graphitic N-doped carbon. exhibited modulated electron density Co active sites, promoted O2 release, an enhanced transfer rate on heterogeneous interface CoFe Fe2O3. Additionally, introduction highly conductive improved electrical conductivity. Consequently, demonstrated excellent performance stability for 1 M KOH. Notably, competitive performance, requiring overpotentials only 166 282 mV at 10 100 mA cm–2, respectively. This places among most efficient, far we know. work provides example rational design electrocatalysts.

ABSTRACT Carbon electrocatalyst materials based on lignocellulosic biomass with multi‐components, various dimensions, high carbon content, and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently. Due to the catalytic deficiency of neutral atoms, usage single lignocellulosic‐based electrocatalysis involving energy storage conversion presents unsatisfactory applicability. However, atomic‐level modulation lignocellulose‐based can optimize electronic structures, charge separation, transfer processes, so forth, which results substantially enhanced performance carbon‐based catalysts. This paper reviews recent advances rational design as electrocatalysts from an perspective, such self/external heteroatom doping metal modification. Then, through systematic discussion principles reaction mechanisms catalysts, prepared catalysts rechargeable batteries are reviewed. Finally, challenges improving prospects diverse review contributes synthesis strategy via modulation, turn promotes lignocellulose valorization for conversion.
