Abstract
Carbide-derived carbons produced by chlorination of titanium carbide at 600, 800, or 1100
°C were subjected to a post-treatment at 600
°C in Ar, H
2, or NH
3 atmosphere. Experimental results suggest that the chlorination temperature influences the ordering of carbon in a manner that impacts specific surface area and porosity. Higher chlorination temperatures lead to higher total pore volume and increased ordering, but lower microporosity. The effect of post-treatments on surface chemistry is pronounced only for samples chlorinated at 600
°C; post-treatments in Ar are shown to be less effective for chlorine removal than those performed in H
2 or NH
3. Post-treatments in Ar result in a lower total pore volume compared to the ones in H
2 or NH
3 for the same chlorination temperature. Samples chlorinated at higher temperatures contained less oxygen functionalities than samples chlorinated at 600
°C, and showed correspondingly less desorption of H
2O, possibly due to diminished uptake of ambient water.
