Abstract
The adsorption of nitrogen has been measured at 78K. for three artificial graphites and one carbon black, which have been brominated to saturation and then debrominated by heat-treatment under vacuum or in the presence of an inert gas over a range of temperatures. When the graphite of smallest area was brominated it did not return to its original area even after heat-treatment at 1000C., whereas the graphite of largest area exceeded its original area when it was brominated and heated at 1000C. The surface area of the brominated carbon black was restored to the original value when it was evacuated at 400C. After evacuation at 600C., the surface area was greater than that of the original carbon black, but fell to a value less than the original area when the sample was evacuated at 1200C.
