Abstract

The practical application of metal-organic framework (MOF)-derived catalysts in advanced oxidation processes (AOPs) is often hindered by challenges in recoverability and stability in complex water matrices. To overcome these limitations, we developed a scalable strategy to fabricate N-doped carbon nanofibers with coexisting atomic Co sites and metallic Co nanoparticles (Co-N/C) by electrospinning…
