Fabrication of aligned carbon nanotubes on Cu catalyst by dc plasma-enhanced catalytic decomposition

Large-Scale Synthesis of Carbon Nanomaterials by Catalytic Chemical Vapor Deposition: A Review of the Effects of Synthesis Parameters and Magnetic Properties

“…It is generally accepted that the morphology, size and yield of the obtained carbon nanomaterials are critically determined by the kind of catalyst used [ 88 , 89 , 90 , 91 ]. Moreover, as shown in Table 2 , other inorganic materials such as Cu [ 92 ], Au [ 93 ], Cu-Cr [ 94 ], Pd-Cr-Pt [ 95 ], Cs 2 CO 3 [ 96 ], Li 2 CO 3 [ 97 ] and K 2 CO 3 [ 97 ] were also used as catalysts. Across the iron-, nickel- and cobalt-based catalysts, Klinke et al [ 98 ] observed that the Fe catalyst gave the highest selectivity to CNTs in the catalytic decomposition of acetylene at temperatures ranging from 580 to 1000 °C.…”

Recent Research Progress of Carbon Nanotube Arrays Prepared by Plasma Enhanced Chemical Vapor Deposition Method

“…Prior to CNT deposition, catalyst film can be broken into nanoparticles by plasma bombardment. Thicker catalyst film makes larger nanoparticles, but decreased density of CNTs with larger diameters and lower quality [24]. Catalyst film can not be sufficiently transformed into nanoparticles when the pre-treatment time of plasma is too short; nonetheless, the catalyst nanoparticles will aggregate result from Ostwald Ripening [25] with too long time.…”
