Abstract (english)
As bifunctional oxygen evolution/reduction electrocatalysts, transition-metal-based single-atom-doped nitrogen-carbon (NC) matrices are promising successors of the corresponding noble-metal-based catalysts, offering the advantages of ultrahigh atom utilization efficiency and surface active energy. However, the fabrication of such matrices (e.g., well-dispersed single-atom-doped M-N-4/NCs) often requires numerous steps and tedious processes. Herein, ultrasonic plasma engineering allows direct carbonization in a precursor solution containing metal phthalocyanine and aniline. When combining with the dispersion effect of ultrasonic waves, we successfully fabricated uniform single-atom M-N-4 (M = Fe, Co) carbon catalysts with a production rate as high as 10 mg min(-1). The Co-N-4/NC presented a bifunctional potential drop of Delta E = 0.79 V, outperforming the benchmark Pt/C-Ru/C catalyst (Delta E = 0.88 V) at the same catalyst loading. Theoretical calculations revealed that Co-N-4 was the major active site with superior O-2 adsorption-desorption mechanisms. In a practical Zn-air battery test, the air electrode coated with Co-N-4/NC exhibited a specific capacity (762.8 mAh g(-1)) and power density (101.62 mW cm(-2)), exceeding those of Pt/C-Ru/C (700.8 mAh g(-1) and 89.16 mW cm(-2), respectively) at the same catalyst loading. Moreover, for Co-N-4/NC, the potential difference increased from 1.16 to 1.47 V after 100 charge-discharge cycles. The proposed innovative and scalable strategy was concluded to be well suited for the fabrication of single-atom-doped carbons as promising bifunctional oxygen evolution/reduction electrocatalysts for metal-air batteries.
