Nippon Steel & Sumikin Chemical Co Ltd developed the "Escarbon" porous carbon material in collaboration with Nobuyuki Nishi, a professor emeritus at the Institute for Molecular Science, and started to provide samples of the material.

The precursor of the Escarbon is a metal acetylide made by combining acetylene carbon and metal atom. It has a structure that can be controlled in increments of nanometers and is called "mesoporous carbon nano dendrite (MCND)."

The MCND has a dendrite structure with fine pores separated by graphene sheets. It is a porous material having mesopores with a diameter of 2-50nm and micropores with a diameter of less than 2nm. With a dendritic spatial structure, it has a high gas-liquid diffusivity. Moreover, it has high electric conductivity and durability.

The MCND is expected to be used for battery materials, catalyst carriers, gas-absorbing materials, etc. And Nippon Steel & Sumikin Chemical is considering using it for fuel-cell materials. The company plans to provide samples for various applications, establish volume production technologies and expand the product line of the Escarbon series.
