Micro- and mesoporous carbide-derived carbon …

Chlorine treatment of the resulting mesoporous silicon carbide was performed in a quartz tube (inner diameter 25 mm) in a horizontal tubular furnace. After argon purging (150 ml min −1 ) at room temperature (RT), the sample was heated to 800 °C (heating rate 450 K h −1 ) and the gas flow changed to a chlorine/argon (80 ml min −1 /70 ml min −1 ) mixture for 3 h.
