Abstract: Halogenated graphene nanoplatelets that are characterized by having, except for the carbon atoms forming the perimeters of the graphene layers of the nanoplatelets, (i) graphene layers that are free from any element or component other than sp2 carbon, and (ii) substantially defect-free graphene layers; the total content of halogen in the nanoplatelets is about 5 wt % or less calculated as bromine and based on the total weight of the nanoplatelets. Processes for producing such nanoplatelets and various end uses for such nanoplatelets are also described. Halogenated exfoliated graphite having a total content of halogen of about 5 wt % or less calculated as bromine and based on the total weight of the halogenated exfoliated graphite and processes for producing the halogenated exfoliated graphite are also provided.

Abstract: This invention provides process for forming a binder slurry, which process comprises: A) mixing halogenated graphene nanoplatelets and one or more polar solvents to form a nanoplatelet slurry, and combining the nanoplatelet slurry and one or more binders to form a binder slurry; or B) combining i) a nanoplatelet slurry comprising halogenated graphene nanoplatelets in a polar solvent with ii) one or more binders to form a binder slurry. The halogenated graphene nanoplatelets comprise graphene layers and are characterized by having, except for the carbon atoms forming the perimeters of the graphene layers of the nanoplatelets, (a) graphene layers that are free from any element or component other than sp2 carbon, and (b) substantially defect-free graphene layers, wherein the total content of halogen in the nanoplatelets is about 5 wt % or less calculated as bromine and based on the total weight of the nanoplatelets.

Abstract: Thermally-activated cellulosic-based carbon is rendered more thermally stable by exposure to a halogen and/or a halogen-containing compound. Such treated cellulosic-based carbon is suitable for use in mitigating the content of hazardous substances in flue gases, especially flue gases having a temperature within the range of from about 100° C. to about 420° C.
