- The GO employed as a catalyst for these studies was prepared from natural flake graphite using the Hummers method;[5]however similar results were obtained when GO was prepared using the Staudenmaier method (see Table 1).[6]

- The BET surface area of the GO starting material (0.7 m2 g−1) was similar to that measured for the reduced product obtained after the oxidation reaction (3.2 m2 g−1).

- At high initial loadings (≥50 wt %) no change in activity was observed for up to 10 cycles. However at low catalyst loadings (≤20 wt %) the recovered catalyst exhibited only approximately 5 % conversion of PhCH2OH into PhCHO after 24 h at 100 °C. Hence as the alcohol oxidation reaction proceeds the catalyst may undergo reduction to a point such that reversion to GO is no longer favored under ambient conditions.

- In some of the oxidation reactions described the initial heterogeneous dispersion stabilized upon heating/stirring. The respective catalyst was conveniently separated by dissolution of the product mixture in methylene chloride or chloroform followed by filtration of the precipitated solids. There was no loss of the carbon content of the employed catalyst during the reaction based on elemental analysis data; however the total mass of the catalyst decreased as it lost a portion of its oxygen functionality and was reduced.
- Similarly benzylamine was converted into benzaldehyde (28 % conversion; conditions: 50 wt % GO 75 °C 24 h). Presumably the reaction proceeded through the respective imine which underwent rapid hydrolysis. In contrast 1‐butanol allyl alcohol 2‐mercaptoethanol and 2‐(methylthio)ethanol showed little or no conversion into their oxidized products under any of the conditions tested.
