Highly dispersed bimetallic alloy nanoparticle electrocatalysts have been demonstrated to exhibit exceptional performance in driving the nitrate reduction reaction (NO3RR) to generate ammonia (NH3). In this study, we prepared mesoporous carbon nanofibers (mCNFs) functionalized with ordered PtFe alloys (O-PtFe-mCNFs) by a composite micelle interface-induced co-assembly method using poly (ethylene oxide) -block-polystyrene (PEO-b-PS) as a template. When employed as electrocatalysts, O-PtFe-mCNFs exhibited superior electrocatalytic performance for the NO3RR compared to the mCNFs functionalized with disordered PtFe alloys (D-PtFe-mCNFs). Notably, the NH3 production performance was particularly outstanding, with a maximum NH3 yield of up to 959.6 µmol/ (h · cm²). Furthermore, the Faraday efficiency (FE) was even 88.0% at -0.4 V vs. reversible hydrogen electrode (RHE). This finding provides compelling evidence of the potential of ordered PtFe alloy catalysts for the electrocatalytic NO·RR. [ABSTRACT FROM AUTHOR] |
