POROUS CARBON MATERIAL, PROCESS FOR PRODUCING THE SAME, ADSORBENT, MASK, ADSORBENT SHEET AND SUPPORTING MEMBER

摘要

A process for producing a porous carbon material from a plant-derived material as a raw material, including carbonizing a plant-derived material at 800° to 1400°C and treating the carbonized matter with an acid or alkali. According to the process, a porous carbon material of 10 m²/gram or more specific surface area according to the nitrogen BET method, 1 wt.% or less silicon content and 0.1 cm³/gram or more pore volume can be obtained from a plant-derived material of 10 wt.% or more silicon content as a raw material. By this process, there can be obtained a porous carbon material of excellent functionality finding applicability in, for example, a negative electrode material of battery, adsorbent, mask, adsorbent sheet and supporting member.
