This review summarizes the main achievements in the controlled synthesis of CNTs and CNT hybrids, focusing on chirality-specific growth and synthesis of one-dimensional materials with CNT templates. The design of structural templates, growth mechanisms, and various types of 1D hybrids templated by CNTs are discussed, addressing the main advantages, challenges, and perspectives in further development.
Carbon nanotubes (CNTs) present unique properties determined by their chiral structure. The main hurdle towards the wide applications is the difficulty to control the structure of CNTs and their hybrids that determines the properties. Precise synthesis with well-defined templates is a promising approach to control the identical structure of carbon nanomaterials. In this review, we summarize main achievements on controlled synthesis of CNTs and hybrids on two aspects: chirality-specific growth of CNTs from well-defined catalysts and nanocarbon templates, atomically precise synthesis of one-dimensional (1D) materials with the templates of CNTs. In the chirality-controlled growth part, we focus on the design of structural templates and growth mechanisms. In the synthesis of CNT hybrids part, we organize the existing strategies based on types of 1D hybrids templated by CNTs, including confined nanotubes, linear carbon chains, nanowires, quasi-1D van der-Waals materials. The main advantages, challenges, and perspectives in further development are discussed.
