Controlled growth of nao-carbon metarials based on anodic aluminum oxide nano-template
The reactions were carried out by decomposing acetylene at 700 ℃ in a two-stage furnace system under different conditions.In the two furnaces,an AAO template with the average diameter about 50 nm was placed respectivly,whose temperature was designed to be 700 ℃.The samples were characterized by scanning electron microscopy and high resolution transmission electron microscopy.The results show that when the reaction was carried out in C2H2-Ar atmosphere,dense and entangled CNTs with diameter,ca.50 nm were obtained on the top surface of the AAO template in the first furnace and dense and entangled CNTs with morphology of rope were obtained on the top surface of the AAO template in the second furnace.When the reaction was carried out in C2H2-H2-Ar atmosphere,dense and entangled CNTs with diameter,ca.50 nm were obtained on the top surface of the AAO template in the first furnace,however only a few CNTs were obtained in the second furnace.When the reaction was carried out in C2H2-H2 atmosphere,CNTs were both observed stood on the top of AAO template in the two furnaces.
