摘要：

Ordered porous carbon with tailored pore size represents an innovative concept in electrochemical hydrogen storage. This work deals with physical characteristics and electrochemical hydrogen storage behavior of the ordered porous carbons with well-tailored pore size, synthesized by a replica technique using hexagonal mesoporous silica as templates. By using a mixture of two surfactants (HTAB and C16EO8) at different ratios, it is possible to control the wall thickness of silica and, consequently, the pore diameter of carbons within a narrow range of 2.1-2.8 nm. In addition, highly developed ultramicroporosity (pore size smaller than 0.7 nm), which plays a predominant role in hydrogen storage, can be produced in the ordered porous carbons. A discharge capacity of up to 527 mAh/g (corresponding to 1.95 wt % hydrogen storage) has been achieved in 6 M KOH for the ordered porous carbon. Furthermore, the ordered porous carbons also possess excellent capacity retainability after charge-discharge cycles and rate capability.
