POROUS BODY AND METHOD FOR MANUFACTURING SAME, STRUCTURAL ELEMENT, POWER STORAGE DEVICE, CATALYST, TRANSISTOR, SENSOR, SOLAR CELL, LITHIUM CELL, AND VAPORIZING DEVICE

摘要

A porous body provided with a carbon structure (20) having pores, the average size of the pores being 2 µm or less and the minimum size thereof being at least 60 nm. A porous body provided with a porous metal (10) and a transition metal chalcogenide film (24) having a layered structure provided so as to cover a surface of the porous metal. A method for manufacturing a porous body, the method including a step for heat-treating a porous metal (10) formed by dealloying so that the size of pores (12) and ligaments (14) increases, and a step for forming a carbon structure (20) having a Dirac-cone-type electronic state density on a surface of the porous metal, the step for heat treatment being performed before or simultaneously with the step for forming a carbon structure.
