Abstract: Compositions are disclosed for carbon supported catalysts with high metal loadings, high electrochemically active surface area, and good water management properties. In one aspect, the invention is directed to a carbon supported catalyst comprising a carbonaceous substrate and a dispersed metal, wherein the carbonaceous substrate has an electron microscopy surface area to nitrogen surface area ratio of at least 0.5 and a nitrogen surface area of at least 100 m2/g.

Abstract: A process for the oxidation of carbon black with an aqueous mixture of hydrogen peroxide where carbon blacks are mixed with aqueous hydrogen peroxide then dried in order to efficiently oxidize industrial quantities of carbon black using standard carbon black production equipment and production rates and under conditions that produce no hazardous emissions and require no special handling.

Abstract: A pigment dispersion of enhanced viscosity and heat stability characteristics for use in coating systems is provided. The pigment dispersions generally comprise a pigment carrier, a pigment of the type having a hydrophilic surface, and a surfactant functional as a dispersant in a relatively non polar matrix and which is present on the surface of the pigment in an effective amount. Pigment carriers include water-based carriers and organic solvent-based carriers. Finished coatings having improved viscosity and heat stability are also provided. The finished coatings comprise a coating base and the surfactant treated pigments. Such pigments include iron oxide pigments yellow iron oxide pigment, black iron oxide pigment, divalent ferrite pigments, zinc ferrite pigment, and magnesium ferrite pigment. Such surfactants include trimethylol propane, and trimethylol ethane.

Abstract: There is provided a pigment concentrate dispersible in plastics and having a substantially improved characteristic extrusion screen life, comprising a dispersion in a resin carrier of an inorganic pigment of the type having a hydrophilic surface, having on its surface in an effective amount a surfactant of the type characterized by an attached polar terminus, in relation to the surface of the pigment, and an unattached nonpolar terminus, in relation to the carrier resin, or of the type characterized by a high molecular weight surface blocking agent. Such pigments include iron oxide pigments, red iron oxide pigment, yellow iron oxide pigment, black iron oxide pigment, divalent ferrite pigments, zinc ferrite pigment, and magnesium ferrite pigment. Such surfactants include dimethyl polysiloxane, isopropyl triisostearoyl titanate, trimethylol propane, trimethylol ethane, and low molecular weight polyethylene.
