description | [Image: see text] The global spread of severe acute respiratory syndrome coronavirus 2 has led to a widespread surge in the use of disposable medical face masks (DFMs) and waste nitrile gloves (WNGs). To address the immense disruption in waste management systems, the catalytic pyrolysis of DFMs and WNGs was undertaken to yield multiwalled carbon nanotubes. Two MgO-supported bimetallic catalysts, Fe–Co and Fe–Ni, were synthesized for catalytic pyrolysis. The MgO-supported Fe and Co catalysts showed a good yield of N-doped CNTs (N-CNTs) above 33 wt %, while the percentage of WNGs did not exceed 20 wt %. The pyrolysis process resulted in the formation of Fe–Co microspinels, which were subsequently encapsulated within N-CNTs, ultimately yielding FeCo-NCNTs. The synthesized FeCo-NCNTs were approximately 25 nm in diameter and were extended over several micrometers in length. Subsequent evaluations included testing several acid-washed FeCo-NCNTs as catalysts for the oxygen reduction reaction. The FeCo-NCNTs exhibited remarkable catalytic performance, with a half-wave potential at 0.831 V (vs RHE) and exceptional resistance to methanol poisoning. These remarkable findings have the potential to contribute to the sustainable recycling of waste generated during the COVID-19 pandemic and to the utilization of waste-derived materials. |
