摘要:
Methods and processes for synthesizing high quality carbon single-walled nanotubes (SWNTs) are provided. A carbon precursor gas at reduced concentration (pressure) is contacted with a catalyst deposited on a support and at temperature about 10 0C above the SWNT synthesis onset temperature, but below the thermal decomposition temperature of the carbon precursor gas for given growth conditions. The concentration (pressure) of the carbon precursor gas can be controlled by reducing the total pressure of the gas, or by diluting with an inert carrier gas, or both. The methods produce SWNTs with the ratio of G-band to D-band in Raman spectra (I G :I D ) of about 5 to about 200.
摘要(中):
提供了合成高品质碳单壁纳米管(SWNT)的方法和工艺。 将降低浓度(压力)的碳前体气体与沉积在载体上的催化剂和高于SWNT合成起始温度约10℃的温度接触,但低于给定生长条件下碳前体气体的热分解温度。 碳前体气体的浓度(压力)可以通过降低气体的总压力或通过用惰性载气稀释或两者来控制。 该方法产生具有约5至约200的拉曼光谱(IG:ID)中的G带与D带的比率的SWNT。
