Abstract

PAN-based ACNFs incorporated with MgO was prepared by electrospinning process followed by appropriate activation process. The addition of MgO caused physicochemical changes in term of smaller fiber diameter with an average diameter of 520 nm and higher surface area which is up to four times ($1893m^2\;g^{-1}$) as compared to pristine ACNFs ($478m^2\;g^{-1}$). Moreover, the modified ACNFs possessed a better adsorption capacity with higher $CH_4$ adsorption of $2.37mmol\;g^{-1}$. From the experimental data, the adsorption of $CH_4$ by composite ACNFs obeyed the pseudo-second order kinetic model with $R^2$ value up to 0.9996 and best fitted by Freundlich isotherm model.
