General description

Surface area of the graphitized mesoporous carbon was determined to be 77 m2/g. These are highly pure graphitized, porous carbon nanoparticles. Particles have large mesopores and some microporosity. Graphite lattice structure content of approximately 10%. An agglomeration of 30 nm mesoporous nanoparticles (TEM).

Application

The cytotoxic effects of graphitized carbon mesoporous nanopowder and multiwalled carbon nanotubes (MWNTs) was compared on human airway epithelium. Mesoporous carbon was found to have no effect on the epithelium cell morphology.

Articles

Mesoporous Materials include a range of high surface area porous silicates with applications in gas adsorption, drug delivery, diagnostics and catalysis.

Mesoporous materials are formed by a self-assembly process from combined solutions of sol-gel precursors (e.g., metal alkoxides) and structure-directing amphiphiles, usually block-copolymers or surfactants.

Recent demand for electric and hybrid vehicles, coupled with a reduction in prices, has caused lithium-ion batteries (LIBs) to become an increasingly popular form of rechargeable battery technology.

Solid oxide fuel cells (SOFC) and solid oxide electrolyzers (SOE) are in the early stages of development; however, the performance that has been achieved shows promise for conversion between chemical and electrical energy.
