Abstract: Provided are a sulfide-based lithium-argyrodite ion superconductor containing multiple chalcogen elements and a method for preparing the same. More specifically, provided are a sulfide-based lithium-argyrodite ion superconductor containing multiple chalcogen elements and a method for preparing the same that are capable of significantly improving lithium ion conductivity by substituting a sulfur (S) element in a PS43- tetrahedron with a chalcogen element such as a selenium (Se) element, other than the sulfur (S) element, while maintaining an argyrodite-type crystal structure of a sulfide-based solid electrolyte represented by Li6PS5Cl.

Abstract: Disclosed is a method for infiltrating a porous structure with a precursor solution by means of humidification. The infiltration method with a precursor solution using moisture control comprises the steps of: (S1) providing a substrate having porous structures deposited thereon; (S2) depositing, by electrospraying, a precursor solution on the substrate having porous structures deposited thereon; (S3) humidifying the porous structures having the precursor solution deposited thereon; and (S4) sintering the humidified porous structures.

Abstract: A metal/support catalyst for conversion of carbon dioxide to methane contains a metal including a transition metal and a support containing a perovskite-type oxide, on which the metal is supported. The metal/support catalyst for conversion of carbon dioxide to methane is capable of increasing the catalytic activity of the Sabatier reaction by promoting the formation of hydroxide ions and helping the production of formate, which is a reaction intermediate in the conversion of carbon dioxide to methane, without using a precious metal. In addition, it is capable of conducting the reaction stably for a long period of time.

Abstract: A metal-ceramic composite for a fuel cell anode is disclosed. In the metal-ceramic composite, the content of the metal is greatly reduced and the intervals between the metal particles are maintained constant, achieving improved activity and conductivity. The metal-ceramic composite includes a metal catalyst raw material and a mixed-conductive ceramic. The metal catalyst raw material is present in an amount such that the content of the metal catalyst nanoparticles in the metal-ceramic composite is significantly lower than in conventional metal-ceramic composites. The presence of a small amount of the metal catalyst nanoparticles in the metal-ceramic composite minimizes the occurrence of stress resulting from a change in the volume of the metal catalyst and provides a solution to the problem of defects, achieving improved life characteristics. Also disclosed is a method for preparing the metal-ceramic composite.
