A high‐performance hybrid supercapacitor electrode based on ZnO/nitrogen‐doped carbon nanohybrid

Abstract

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).

“…[67] ZIFs have the potential to improve several applications such as biomedical applications, [20,65] gene delivery, [68][69][70] biomedicine, [71,72] environmental, [15,[73][74][75][76] and energybased applications. [50,51,[77][78][79] They are also promising materials for gas separation/storage. ZIF-8 (Zn-based ZIFs) was reported as a colorimetric sensor for the simple detection of CO 2 .…”

“…Porous materials [1,2] such as Metal-organic frameworks (MOFs) [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] and zeolitic imidazolate frameworks (ZIFs) are hybrid porous materials consisting of metal ions connected with organic linkers [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. Processing MOFs using template materials gives rise to a new class of mixed materials that combines the advantages of both components [21][22][23][24][25][26].…”
