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1000m2/g以上。如果在800℃～870℃炭化，柏木炭外表面积可达400m2/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30m2/g～40m2/g。在900℃以上炭化得到的柏木炭，微孔表面积高达800m2/g以上，外表面积约为150m2/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 1000m2/g without an additional activation process. Cypress charcoals prepared at a temperature of 800－870℃ had a large external surface area of more than 400m2/g, comparable to the microporous surface area, even though only 30－40m2/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 800m2/g and an external surface area of about 150m2/g. The pore structure in cypress charcoals could be controlled by selecting the temperature of the steam.
