  Single-walled carbon nanotubes (SWCNTs) have emerged as a shining material for their potential applications in many fields such as high-strength composites, energy storage, and drug delivery. The chirality of SWCNTs would influence, and even decide their electronic, optical, and magnetic properties. Practical application and large-scale production are hindered by the chirality impurity of as-prepared SWCNTs, which give rise to great necessity of chirality-controlled SWCNT synthesis. Herein, we summarize recent progress in SWCNT synthesis with focus on cloning growth with seeds and epitaxial growth on catalysts as well as the corresponding growth mechanism. A large number of factors such as growing temperature, catalyst composition, particle size, substrate material, and carbon source species were systematically investigated to check to which extent they would affect nucleation rate, growth rate, carbon yield, and chirality selectivity. The interplay between catalyst particles and SWCNTs was also explored both experimentally and theoretically. By manipulating these parameters, some correlative approaches to achieve chiral growth of specific SWCNTs were proposed. We hope that these summaries will help researchers get a better understanding on SWCNT formation and develop more well-designed catalysts with high selectivity and activity.
