The presence of mesopore can be confirmed by the TEM image (Figure ). These observations confirm the formation of hierarchical porous ZIF-8 materials containing micropore and mesopore regimes. TGA data revealed that the material is thermally stable up to 350 o C (Figure ). Above this temperature, the material decomposes to ZnO (Calculated, 35.6%, Found, 32.6%, Figure ). ZIF-8 was used as the precursor for synthesizing ZnO@N-doped C via carbonization. The carbonized material was characterized using XRD (Figure ), XPS (Figure ), TEM (Figure ), HR-TEM (Figure ), and nitrogen adsorption-desorption isotherm (Figure ). The XRD pattern reveals the synthesis of ZnO that is assigned to the hexagonal wurtzite structure of ZnO was fixed at 1.9, 2.2, and 2.2 eV, respectively. These peaks were attributed to pyridine-like nitrogen, pyrrole-like nitrogen, and graphitic nitrogen, respectively. Zn-O and oxygenated carbon components were also observed from XPS O1s at 531 and 532.3 eV, respectively. The FWHM of these peaks was fixed at 2.2 and 2.1 eV, respectively. These XPS results indicate the development of N-doped ZnO embedded carbon graphite. TEM image of ZnO@N-doped C shows dark particles of ZnO dense phase into a gray layer of carbon (Figure ). HR-TEM image shows lattice fringes of 0.28 nm corresponding to Miller index (002) for ZnO (Figure ). Data analysis confirms the synthesis of ZnO@N-doped C via the carbonization of ZIF-8. Nitrogen adsorption-desorption isotherm reveals the presence of mesopore carbon with ZnO (Figure ).
