GAS ADSORPTION MEDIUM AND GAS ADSORPTION PUMP APPARATUS USING THE SAME

摘要

A gas adsorption medium and an adsorption pump apparatus having the same are provided. The gas adsorption medium includes a multi-layered structure of which the layers formed of a material are spaced apart from each other, wherein an ion valence of the material is variable and the material includes extra electrons not participating in a chemical bond, and the adsorption pump apparatus includes the gas adsorption medium as described above. The gas adsorption medium can secure a large surface area by securing a space between the layers so that efficiency of the gas adsorption ability can be enhanced.
