✦ Synopsis

The properties and potential applications of carbon freshly made from high purity CO gas (99.91%) were 2 added to ensure the CO being in a supercritical state nanotubes (CNTs) such as superconductors [1], single-2 (critical point, 31 8C, 73 atm) at high temperatures. A molecular transistors [2,3] and magnetic recording devices typical reaction used 8.0 g CO and 0.5 g metallic Li, in [4] have led to considerable efforts to synthesize CNT 2 which CO was in excess for the oxidation of metallic Li. since their discovery in 1991 [5]. The methods for 2 If not specifically mentioned, most of the reactions were producing CNTs involve laser vaporization of metal-doped conducted at 550 8C, 700 atm for 10 h. The main products carbon targets [6], arc evaporation of metal-doped carbon identified were carbon and Li CO after reaction at 550 8C electrodes [7], decomposition of C H [8] and catalytic
