Abstract

Modification of ZIF-8 with N-CDs through the direct mixing method at room temperature was successfully carried out. XRD confirmed the formation of the N-CDs crystal structure with ZIF-8, characterized by an amorphous peak at 24.83. SEM showed heterogeneous particles with an average diameter of 14 &#956-m. EDX confirmed the composition of C (34.82%), N (37.25%), O (12.60%), and Zn (14.90%), confirming that the samples contained the precursor components utilized. These findings prove N-CDs can be used as a modifier of ZIF-8 without damaging its basic structure, although their abundance affects the material^s morphology.
