Abstract
High surface area nanoporous carbon has been prepared by thermo-chemical etching of titanium carbide TiC in chlorine in the temperature range 200–1200
°C. Structural analysis showed that this carbide-derived carbon (CDC) was highly disordered at all synthesis temperatures. Higher temperature resulted in increasing ordering and formation of bent graphene sheets or thin graphitic ribbons. Soft X-ray absorption near-edge structure spectroscopy demonstrated that CDC consisted mostly of sp
2 bonded carbon. Small-angle X-ray scattering and argon sorption measurements showed that the uniform carbon-carbon distance in cubic TiC resulted in the formation of small pores with a narrow size distribution at low synthesis temperatures; synthesis temperatures above 800
°C resulted in larger pores. CDC produced at 600–800
°C show great potential for energy-related applications. Hydrogen sorption experiments at −195.8
°C and atmospheric pressure showed a maximum gravimetric capacity of ∼330
cm
3/g (3.0
wt.%). Methane sorption at 25
°C demonstrated a maximum capacity above 46
cm
3/g (45
vol/vol or 3.1
wt.%) at atmospheric pressure. When tested as electrodes for supercapacitors with an organic electrolyte, the hydrogen-treated CDC showed specific capacitance up to 130
F/g with no degradation after 10
000 cycles.
