リチウムアセチリドからの多孔質炭素の調製

抄録

Lithium acetylide (LiC=CLi) was easily oxidized by exposure in CO₂ at room temperature, resulting in reaction product mixture composed of carbon and lithium compounds (mainly Li₂CO₃). Porous carbons containing mesopores and macropores were prepared by removal of the lithium compounds using immersion in hydrochloric acid. The pore formation was derived from micro-domain structure consisting of the carbon matrix and the lithium compounds in the lithium acetylide oxidized with CO₂. Furthermore, the macropores and mesopores in the porous carbon were developed by the heat treatment (1000°C) of the oxidized lithium acetylide before the acid immersion.
