In this paper we report the electrochemical behavior of heat-treated carbon blacks and Pt/C catalysts. Cyclic voltammetry indicates that the heat-treated carbon black as catalyst support does not improve the Pt/C catalyst's activity for methanol oxidation. An XPS study of a Pt-loaded carbon black indicates that the amounts of oxidized platinum and oxygen-functional groups on catalysts are decreased when the platinum particles are deposited on the heat-treated carbon surface. These changes in the surface and crystalline structural properties of carbon materials lead to the catalytic activity change in methanol electro-oxidation.

Acetylene Carbon Black

An experimental study has been made of the adsorption of a nitrogen, sulphur dioxide, carbon dioxide, and ammonia on Shawinigan acetylene carbon black and several derivatives of this material produced by heat treatment up to temperatures of 3000°. The effect of the heat treatment of the Shawinigan carbon black on its adsorption of the polar and non-polar gases studied is compared with the behavior of other heat treated carbon blacks. In particular, the effect of the low oxygen content of the Shawinigan black is considered. The isosteric heats of adsorption for ammonia on the most highly graphitized material (Shawinigan 3000) have been calculated. The results are in general agreement with previous calorimetric work of this laboratory. A special type of hysteresis for the system ammonia – Shawinigan black has been observed. This may be due to a reversible swelling of the graphitic material.

Treated Carbon

There are many types of carbon which have the same hexagonal atomic configuration as the layer planes of graphite. These include colloidal carbon blacks and the various cokes, chars and pyrolized fibers that are used commercially. The evaporated carbon films that are utilized in electron microscopy also fit into the same category. Where all these carbons differ from graphite is in their rotational disorder about the c-axis, larger c-spacing (e.g. about 3.5-3.8 Å as compared to 3.35 Å for graphite) and smaller crystallite size.The recent work of Heidenreich, Hess and Ban has demonstrated phase contrast imaging of the graphite lattice in heat treated carbon blacks using axial illumination. The c-spacing of 3.4 Å and numerous other aspects of microstructure were resolved in an ISAF carbon black heated at 2600-3000°C. This type of carbon has been proposed as a high resolution test specimen and as a means of calibrating magnification at high electron optical magnifications.
