Facile Preparation of imidazole-functionalized nanofibers for Cobalt removal from spent lithium-ion batteries.

ABSTRACT: The escalating volume of spent lithium-ion batteries (LIBs) presents a critical challenge for environmental protection and resource sustainability, driving the need for efficient cobalt(II) recovery. To overcome the limitations of conventional adsorbents, such as complex synthesis and poor selectivity, this study developed a novel imidazole-grafted polyacrylonitrile nanofiber composite (Im-g-PAN-NFs) through a facile stepwise functionalization strategy. The material was fabricated via electrospinning followed by sequential grafting with ethylenediamine and 4-methyl-5-imidazolecarboxaldehyde, introducing high-affinity coordination sites. Comprehensive characterization (FT-IR, SEM, XPS, BET) confirmed successful functionalization and revealed a roughened fibrous morphology with enhanced surf
