Here we study the photovoltage generated in novel all-graphene devices based on FeCl 3-intercalated few-layer graphene (FeCl 3 –FLG, dubbed graphexeter) and pristine graphene. The FeCl 3 intercalation is known to dope graphene to record high charge carrier densities (up to ≈9 10 14 cm –2), and it drops the room temperature square resistance of graphene to just a few ohms, making this

A Revisited Mechanism of the Graphite

The graphite-diamond phase transition is a central subject in physical science. Among the debates after many years of studies, one outstanding issue is the role of hexagonal diamond (HD), which was argued to be the preferable product according to the simulation but never reported in the compression experiments on graphite under high-pressure and high-temperature (HPHT) conditions.

Recent Progress of TiO2

Up to now, the vast majority of commercial LIBs rely, at the cathode side, on transition metals oxides or phosphates active material (LiCoO 2 [], LiNiO 2 [], LiMnO 2 [], LiFePO 4 [], LiMnPO 4 [], etc.), while graphite is commonly used as anode active material.Figure 2 is the principle of a typical lithium ion battery; both anodes and cathodes could shuttle lithium ion back and forth between them.

As described above, it is found that the traditional material for graphene preparation is usually the graphite powder, and it makes the graphene too expensive to be mass-produced in the industry. (13) At present, the best method for graphene preparation is the preparation of biomass graphene with high carbon content, low price, and high reserves to prepare graphene instead of graphite in the

Preparation of interference pigments using black graphite

The graphite nanosheet (GNS) pigments contain no heavy metals and are nonfading pigments composed of exfoliated graphite and TiO 2. GNSs, as a novel substrate for interference pigments, were prepared by wet dispersion with a dispersant and a hydrogen peroxide–urea complex to maintain a sheet structure with few defects.

A review of exfoliated graphite

2015/7/26Exfoliated graphite (EG) refers to graphite that has a degree of separation of a substantial portion of the carbon layers in the graphite. Graphite nanoplatelet (GNP) is commonly prepared by mechanical agitation of EG. The EG exhibits clinginess, due to its cellular structure, but GNP does not. The clinginess allows the formation of EG compacts and flexible graphite sheet without a binder. The
