About this Research Topic
With the rapid development of society and the increasing material needs of people, energy shortage has gradually become a significant global issue. Electrochemical technologies (fuel cells, lithium batteries, supercapacitors and electrocatalysts) have great advantages in energy conversion and storage, due to their economical, practical, green and environmentally friendly characteristics. Meanwhile, the preparation and modification of new electrode materials have a key to this research area. Ultrathin two-dimensional (2D) nanomaterials are of great research value in terms of geometry, physics, chemistry, symmetry, characterization instruments and technology concept. As a result, two-dimensional transition metal carbides and nitrides (MXenes), transition metal oxides, transition metal chalcogenides (TMDs), transition metal phosphides, layered double hydroxides (LDHs), precious metal-based materials, metal-organic framework materials (MOFs), covalent organic framework materials (COFs), various polymers, black phosphorous (BP), graphene, silicene, antimonene, inorganic perovskites, and organic-inorganic hybrid perovskites have witnessed rapid development in recent years.
Currently, the most popular methods for preparing ultrathin two-dimensional materials include mechanical exfoliation, ion insertion/exchange assisted liquid exfoliation, selective etched liquid exfoliation, chemical vapor deposition (CVD) and wet chemistry syntheses. However, in order to further explore the intrinsic physical and chemical properties of the ultrathin two-dimensional materials and expand their commercial applications, more novel synthetic strategies are needed, such as non-van der Waals (non-vdW) transformation, frozen growth and salt-templated methods, which have yet to be thoroughly studied and comprehensively developed. Therefore, in this Research Topic, we invite contributions that will stimulate the continuous studies on novel nanotechnologies of Ultrathin 2D materials for energy applications.
We invite submissions of Original Research and Review articles. The areas to be covered in this Research Topic may include, but are not limited to:
• novel synthesis methods for ultrathin 2D materials
• unique synthesis of new ultrathin 2D materials
• in-depth study of the mechanisms involved during ultrathin 2D materials synthesis
• novel extensions to the synthesis of different ultrathin 2D materials
• structural design of new ultrathin 2D materials for improved energy conversion and storage characteristics.
