## Description

- description: "Catalysts' redox reactions are crucial for storage and energy conversion.\r\nTherefore,
    the fabrication of cost-effective, structurally rational, and\r\nmultifunctional
    advanced catalytic materials continues to be a crucial task. In this\r\nstudy,
    we obtained P, Fe, and Co co-doped, nitrogen-rich carbon nanofibers by\r\ndirectly
    forming carbon nanotubes from metal-organic frameworks through\r\nelectrospinning
    and pyrolysis. The P0.025-FeCo/C catalyst demonstrated\r\noutstanding ORR activity,
    including an ECSA of 1954.3 cm², a limited current\r\ndensity of -3.98 mA/cm2,
    an E1/2 of ~ 0.84 V, and an Eonset of ~ 0.94 V. After\r\n5000 cycles, the P0.025-FeCo/C
    catalyst demonstrated remarkable enduring\r\nstability. These function enhancements
    occurred because of the electronic\r\ncoupling between the metal and phosphorus,
    which altered the electron\r\ndistribution at the metal center and optimized its
    electronic structure, thereby\r\nimproving catalytic activity and stability. It
    exhibits good chemical stability in\r\nalkaline media and can maintain its catalytic
    performance for a long time,\r\ndemonstrating good durability. Its tubular structure
    provides many active sites\r\nand superior electron transport paths owing to its
    unique channels and cavities,\r\nwhich help improve its activity and stability.
    Therefore, P0.025-FeCo/C is expected\r\nto become a non-precious metal catalyst
    for facilitating oxygen reduction\r\nreactions."
