Hybrid nanomaterials offer promising properties to serve as an electrode for hybrid supercapacitors. Herein, dye (rhodamine B, RhB) encapsulated zeolitic imidazolate frameworks (RhB@ZIF-8) was synthesized at room temperature via triethylamine (TEA)-assisted method. The material was used as a precursor for synthesizing zinc oxide embedded nitrogen-doped carbon (ZnO@N-doped C) via the carbonization at different temperatures (400 C, 600 C, and 800 C). The materials were characterized using X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential thermal analysis (DTA), highresolution transmission electron microscope (HR-TEM), energy-dispersive X-ray mapping (EDX), nitrogen adsorption-desorption isotherm, and X-ray photoelectron microscope (XPS).
