| 摘 要： | 柏木条经过热蒸气处理,成功地制备了纳米孔炭,无需另行活化,比表面积就可达1000m^2/g以上。如果在800℃～870℃炭化,柏木炭外表面积可达400m^2/g以上,与同样温度在氩气中炭化得到的柏木炭相比,后者微孔面积仅为30m^2/g～40m^2/g。在900℃以上炭化得到的柏木炭,微孔表面积高达800m^2/g以上,外表面积约为150m^2/g。柏木炭的孔结构可以通过调节过热蒸气的温度得到控制。 |

| Abstract: | Nanoporous carbons were prepared from cypress chips under a flow of super-heated steam, and their surface area reached more than 1 000 m2/g without an additional activation process. Cypress charcoals prepared at a temperature of 800-870 ℃ had a large external surface area of more than 400 m2/g, comparable to the microporous surface area,even though only 30-40 m2/g was obtained by carbonization in a flow of Ar gas. Cypress charcoals prepared above 900 ℃ were microporous with a microporous surface area more than 800 m2/g and an external surface area of about 150 m2/g. The pore structure in cypress charcoals could be controlled by selecting the temperature of the steam. |
