Characterization of the prepared KIT-6 silica template, a Low-angle XRD pattern of KIT-6 silica template. b N2 adsorption/desorption isotherm of KIT-6 template. c The corresponding pore size distribution for N2 calculated using a slit pore NLDFT model. TEM images of (d) KIT-6 silica, the OMC carbon samples prepared at (e) 700 oC, (f) 800 oC, and (g) 900 oC, and the HOPC sample (h–i). The insert images are the corresponding Fast Fourier Transform patterns of the selected areas
