Recent advances in transition metal-based electrocatalysts have significantly enhanced the hydrogen evolution reaction (HER) and oxygen (OER) water electrocatalysis. Self-supported electrodes, where active sites are directly integrated with substrates, offer superior kinetics stability compared to traditional powder-based electrocatalysts. The electrospinning technique is particularly effective for fabricating self-supported high surface areas, porosity, uniform distribution of sites, leading improved catalytic performance. Despite extensive research on electrocatalysts, a comprehensive review focusing those developed via remains scarce. This provides detailed overview process, fundamental principles electrocatalysis, recent progress development fabricated through this approach.

Abstract Ammonia electrolysis represents a green and economical strategy for hydrogen production, yet the progress is hindered by lack of efficient catalyst to boost kinetically sluggish ammonia oxidation reaction (AOR). Herein, ternary PtCoSn/C prepared facile wet‐chemical reduction method applied AOR, which exhibits specific activity 0.87 mA cm ECSA −2 , 3 times that Pt/C. The highly enhanced derived from regulated intermediates adsorption on surface, evidenced in situ attenuated total reflection Fourier transform infrared measurements. co‐alloying Co Sn with Pt not only contributes weakened binding strength *OH *H species enhancing NH related intermediates, but also facilitates supply OH − sites, compensating fast consumption double layer during AOR. Benefiting its high evolution reaction, can be used as bifunctional two‐electrode system, requires 0.78 V drive current density 10 . This work sheds light developing AOR catalysts, promoting production electrolysis.
