Research progress on porous carbon materials

Introduction to Carbon Materials Research

A brief historical review of carbon nanotube research is presented and some basic definitions relevant to the structure and properties of carbon nanotubes are provided. Carbon nanotubes are unique nanostructures that can be considered conceptually as a prototype one-dimensional (1D) quantum wire. The fundamental building block of carbon nanotubes is the very long all-carbon cylindrical Single W...

Research Progress of Organic polymer Composite Materials Modified by Carbon Nanotube

Carbon nanotube is a kind of the special structure of material. Its radial length is nano-level and axial length is micron order of magnitude. Both ends of this one-dimensional quantum tube are basically sealed. Several dozens of layers of coaxial pipe is made up of the hexagonal arrangement of carbon atoms. In this paper, the Organic polymer Composite Materials Modified by Carbon Nanotube is i...

Migration mechanism for atomic hydrogen in porous carbon materials

To explain the fast kinetics of H in porous carbon, we propose that the migration relies on H hopping from a carbon nanotube (CNT) to another. Using density functional theory, we have found that the barrier for H hopping becomes smaller than that for diffusion along a tube for certain CNT separations, decreasing to less than 0.5 eV for separations of 3.1 Å. Such significant reduction occurs irr...

Grand Challenges in Carbon-Based Materials Research

CARBON IN ALL FLAVORS: CARBON MATERIALS CONSTITUTE THE MOST VERSATILE MATERIAL GROUP Carbon materials constitute a large family of diverse structures and textures that underlie an increasing range of applications suggested by the impressive number of papers published on this topic. Several hundreds of thousands of publications have appeared since 1900, out of which, thousands were published in ...
