The unique properties of a holey graphene sheet, referred to as sheet with nanoholes in its basal plane, lead wide range applications that cannot be achieved by nonporous counterpart. However, the large‐scale solution‐based production requires oxide (GO) or reduced GO (rGO) starting materials, which take hours days for fabrication. Here, an unexpected discovery without holes can controllably, directly, and rapidly (tens seconds) fabricated from graphite powder via one‐step‐one‐pot microwave...
Hummers method is commonly used for the fabrication of graphene oxide (GO) from graphite particles. The oxidation process also leads to cutting sheets into small pieces. From a thermodynamic perspective, it seems improbable that aggressive, somewhat random oxidative could directly result in nanosheets without destroying intrinsic π-conjugated structures and associated exotic properties graphene. In method, both KMnO4 NO2+ (nitronium ions) concentrated H2SO4 solutions act as oxidants via...
A new mechanism of O2 reduction, which follows principles different from those generally accepted for describing ORR reduction on heteroatom-doped carbons, is suggested. It based the ability oxygen to strongly adsorb in narrow hydrophobic pores. In this respect, a cellular vitreous carbon foam–graphene oxide composite was synthesized. The materials were doped with sulfur and nitrogen and/or heat-treated at 950 °C order modify their surface chemistry. resultant samples presented...
We report on magnetic susceptibility, NMR, and EPR measurements of pristine Fe-doped micro- nanosized graphenes (LGr NGr), prepared by a unique microwave enabled technique from graphite particles. Significant orbital diamagnetism in the studied compounds (∼70% that bulk graphite) is revealed. At T < 30 K, weak paramagnetism due to edge π-electronic spin states observed. Reduction lateral size graphene sheets results suppression strengthening paramagnetic contribution an increased number open...
An ecofriendly approach for graphene fabrication is developed, where no toxic and metal containing compounds were used byproducts generated.
Assisted by microwave heating, a fast, one-step approach is developed H. He and co-workers on page 3358 for the controllable fabrication of holey graphene oxide sheets (HGO) directly from graphite powder. These HGO can be simultaneously reduced doped with heteroatoms quickly at low temperatures. The existence nanoholes not only provides shortcut efficient mass transport, but also dramatically increases amount edges accessible surface area, creating more effective catalytic centers.
