| Research Abstract |
Simple direct synthesis of metal oxides loaded carbon papers was investigated by using bacterial cellulose gel, so-called nata de coco, with nano-sized fibrous morphology. The cellulose gels were immersed in various metal ions (e.g. Mo, Mn, etc.) aqueous solutions to impregnate the metal ions into the gel structures. The gels including metal ions were dried, pressed, and then heat-treated in N2 flow to obtain metal oxides loaded carbon papers. It was found that metal oxides were successfully formed in the carbon matrix by reacting with oxygen of cellulose resource. In addition, the fibrous morphology of raw cellulose was kept after carbonization accompanied with development of micropores. The carbon papers with metal oxides were characterized as binder less porous carbon electrodes for super capacitor using aqueous electrolyte. The larger pseudo capacitance due to redox reactions of the metal oxides was additionally observed to usual electric double layer capacitance of porous carbon.
