This study highlights the successful development of a well-decorated CPB/ZIF-8 nanocomposite, demonstrating significant improvements in photocatalytic performance. We achieved a uniform and well-distributed composite with enhanced functionality by employing the hot-injection method for CPB NC synthesis and integrating them with ZIF-8 through an optimized mixing technique. Electron microscopy (EM) analysis revealed a remarkable distribution of larger CPB NCs across the ZIF-8 framework, exhibiting a uniform and orderly coverage that suggests a highly controlled attachment mechanism. This well-defined assembly is likely driven by surface charge interactions, emphasizing the nanoscale precision of the integration process. Fourier-transform infrared spectroscopy (FTIR) analysis provided key insights into the attachment mechanism, showing a notable reduction in CPB ligand peak intensity. This spectral shift confirms ligand exchange while highlighting the crucial role of surface charge interactions in enabling the incorporation of CPB NCs into the ZIF-8 structure.
