摘要
The study of 28 porous carbons shows that the specific capacitance in the electrolyte (C2H5)(4)NBF4/acetonitrile is relatively constant between 0.7 and 15 nm (0.094 +/- 0.011 F m(-2)). The increase in pores below 1 nm and the lower values between 1 and 2 nm reported earlier are not observed in the present work.
