Microwave assisted exfoliation and reduction of graphite oxide for ultracapacitors

(HK) methods. Further studies are needed to control the pore size distributions for specific applications, for example, increasing micropore volume for hydrogen storage. In summary, using SiCx fibres derived from the pyrolysis of the hybrid precursor fibres of PCS and pitch, a proper control of the activation conditions can yield the co-axial porous composite fibres with high SSA. The porosity and component of the activated fibres may be adjusted by facile control the activation conditions. This kind of core–shell structured fibres can be regarded as Si-substituted activated carbon fibres, which may be promising functional materials, for example, as potential hydrogen storage materials and catalyst sup- ports. This approach can also be adopted for the preparation of M-substituted activated carbon fibres if M-containing poly- mers (or blends) are used as the starting material.
