以表面活性剂F-127、导电玻璃(ITO)为基底制备了三维体心立方结构(Im3m)的介孔SBA-16膜.该膜的(111)晶面垂直于ITO基底.采用电化学沉积技术将少量Fe沉积进入SBA-16膜的孔底,沉积Fe后的SBA-16膜于700℃下乙炔裂解生长碳纳米管,在SBA-16膜(孔)内生长直径均匀、间距相等的开口碳纳米管阵列.采用二次电沉积法可以制备高度有序的填充Fe的碳纳米管阵列.TEM的研究结果表明填充进碳纳米管的Fe具有单晶结构.

关键词: SBA-16膜, 碳纳米管阵列, 填充Fe的碳纳米管

Continuous mesoporous silica thin films with three-dimensional (3D) accessible pore structures (Im3m space groups) have been prepared by a dip-coating technique using F-127 surfactants on indium-tin oxide glass (ITO). The films are oriented with the (111) crystal plane perpendicular to the surface of the film. Deposition of iron metal into the mesopores of SBA-16 films was achieved by using an electrochemical method. And carbon nanotube arrays were fabricated by catalytic decomposition of acetylene at 700℃ using Fe (catalyst) deposited in the pore bottom of SBA-16 films. The CNT arrays grown out of SBA-16 film are very uniform in diameter and hollow with open ends. The second-step electrochemical deposition method was used for preparing a highly ordered array of carbon nanotubes filled with metal Fe. The result of TEM indicates that Fe nanowire deposited in CNT is crystalline.

Key words: mesoporous silicate SBA-16 film, CNT array, CNT filled with Fe
