A layered Fe-Fe hydroxide (green rust, GR) was intercalated with dodecanoate (known as GR) and then amended with Cu (GR(Cu)) before reaction with chloroform (CF), carbon tetrachloride (CT), trichloroethylene (TCE) or tetrachloroethylene (PCE). Reduction of CT by GR(Cu) was 37 times faster than with GR alone before the active Cu species was consumed. The Cu mediated reaction followed the dichloroelimination pathway as observed for GR alone, with carbon monoxide (82.

Expansion of the graphite layers leads to a dramatic 20-fold increase in the yield of high-shear exfoliation. Large graphite flakes, which do not produce graphene upon high shear if left untreated, are exfoliated in a yield of 16.
