Fig. 1: Structure of highly porous graphitized carbon.
From: Sub-millisecond lithiothermal synthesis of graphitic meso–microporous carbon
A Schematic the lithiothermal synthesis of highly porous graphitized carbon at ultrahigh temperature generated by the reaction between PTFE powder and molten Li. B TEM and C HR-TEM of highly porous graphitized carbon, while the former demonstrates highly porous microstructure and connected pore channels for the products, there is variation in focus across the image because of the sloped nature of the sample and changes in sample thickness, the later shows that the products consist of a cluster of nano onions with the lattice spacing between the bent graphitic layers close to 0.36 nm. The image exhibits the presence of a dense network of nanometer-scale pores surrounded by highly graphitized multi-carbon layers. Scale bar: 100 nm (B) and 5 nm (C). D N2 adsorption/desorption isotherms and pore size distribution (inset) of the sample.
