Dear Colleagues,

Low-dimensional nanomaterials (including two-dimensional, one-dimensional, and zero-dimensional) exhibit unique and interesting properties and show application prospects in various fields. Today, different synthetic methods have been used to prepare low-dimensional nanomaterials. The growth conditions and post-treatment process of low dimensional materials have a great impact on the structure and properties of materials. In addition, defect construction and surface engineering are effective methods to optimize the properties of low-dimensional nanomaterials. The in-depth study of crystal growth kinetics, intrinsic lattice defects, and crystal structure of low-dimensional materials is helpful to understand the basic physics and chemical properties and explore new applications. The aim of this Special Issue is to understand the relationships between the crystal structure, chemical composition, and morphology of low dimensional nanomaterials and their physical/chemical properties. Potential applications in the fields of energy conversion and storage. Both original research and review papers are welcome for possible publication.
