AbstractIn this paper, we investigate on the preparation of waste cotton fabric-based activated carbons by different methods. Two different kinds of carbon materials are prepared from waste cotton fabric, the structure and properties were characterized using instrumental analyses such as scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). It is revealed that the products prepared using one-step process are composed of macroporous carbon network , which looks like sponge-type morphology, and exhibit the high values of qiodine(1,198 mg/g) and qmb(235.6 ml/g), showing their potential usage as adsorbent.

N-doped meso/macroporous carbon materials were synthesized by using melamine-formaldehyde resin as carbon precursor and silica spheres as a removable template. Scanning electron microscopy images reveal that the macropores of carbon materials can be modulated by changing the diameter of template. While the BET results verify that the template had no obvious effect to the mesopores of the materials. The as-synthesized carbon materials with a bimodal pores structure display a high surface nitrogen content of 30wt%. XPS analysis reveals that N atoms are mostly bound to the graphitic network in two forms, i.e. pyridinic and pyrrolic nitrogen.
