The activated CNFs with reduced GOs (r-GO) revealed a specific surface area and adsorption capacity of 631 m(2)/g and 191.2 F/g, respectively, which are significantly higher than those of pure CNFs (16 m(2)/g and 3.1 F/g). It is believed that rough interfaces between r-GO and CNFs introduce oxygen pathways during activation, help to produce large amounts of all types of pores compared to pure activated CNFs.
