Electrochemical devices comprising graphene

A method of making a graphene anode, comprising:

• providing a substrate;
• depositing a graphene layer on the substrate, wherein the graphene layer comprising graphene having a substantially micro-crystalline grain size ranging from about 2.0 nm to about 15 nm, basal planes that are substantially planar, and exhibits an anodic potential of at least 2 volts to about 3 volts;
• exposing the graphene layer to a support layer comprising an adhesive or that has been exposed to a component that facilitates adhesion;
• and
• removing the substrate from the graphene layer.

A method, comprising:

• passing non-potable water between a graphene anode and a cathode, wherein the graphene anode comprises graphene having a substantially micro-crystalline grain size ranging from about 2.0 nm to about 15 nm, basal planes that are substantially planar, and exhibits an anodic potential of at least 2 volts to about 3 volts;
• applying an electric current using a power source;
• and
• isolating potable water.
