Single-walled carbon nanotubes (SWCNTs) as a promising candidate in a wide range of applications have shown great potentials in optical, electronic, magnetic and mechanical fields. Precisely due to their excellent characteristics and performances, it has attracted widespread attention, and much progress has been made during recent decades. However, due to the huge challenge in controlled synthesis and purification, obtaining SWCNTs with consistent chirality has seriously limited their high-end industrial applications. In this article, we will review the approaches recently developed in chirality-controlled preparation of SWCNTs. Among them, we will introduce the mechanism of templated growth of SWCNTs from chiral affinities, including cloning and seeds designing strategies. The preparation of SWCNTs catalyzed by noble metal and assisted with weak oxidant have been illustrated as well. Meanwhile, we will also discuss some chirality-selective separation approaches, which pay more attention to post-processing strategies by purifying the chiral SWCNTs with functional reagents. We expect that these strategies in controlling the chirality of CNTs will shed more light on the mechanism and process for atomic structural control of CNTs, and may also be applicable in the controlled synthesis of other nanomaterials.
